波长精度与扫描速度的完美结合

Spark的高速单光栅的创新设计在5秒内提供了200-1000纳米的吸收光谱,使用的阶跃尺寸仅为1纳米,有效地消除了样品蒸发的风险。光谱记录以无与伦比的波长精度和再现性(<=0.3nm)进行,为每个样品生成一致的数据。

这种速度、准确度和重现性的结合使Spark成为小体积核酸定量和纯度检测的首选仪器。

The image shows OD linearity from 0 to 4 OD measured at 260 nm.

核酸定量分析的优越表现

Spark卓越的波长精度和再现性,结合帝肯Nanoquant Plate™的独特设计,保证DNA检测下限为<1 ng/μl。

A260/280或A260/230中良好的波长比精度对于DNA/RNA纯度检测至关重要,它们的精度是确保数据的重现性,但市场上大多数检测器系统都没有特定参数设定。

Spark的超快速的光谱记录使您能够在不存在蒸发风险的情况下对NanoQuant 中的所有16个样品进行全光谱波长扫描。而这个风险对于其他的基于单色仪的吸收光检测仪是一个已知的风险点。

NanoQuant微量检测板

无需校准的小量核酸定量

已获专利的NanoQuant微量检测板是首款专为小量核酸多功能酶标仪吸光度分析而设计的工具。其适用于广泛的应用,如DNA或RNA定量、核酸纯度评估和标记效率测定。

展示更多

无需校准量的定量板

NanoQuant 板可以同时检测多达16个样本,样本体积仅为2uL。可以使用传统的单道或八道移液器完成加样。每一个石英微点都是当作一个单独的透镜使用—这样保证了每个样本的光的通过性——并可以被快速、容易地清洁以最大的限度去降低交叉污染的风险。关上板盖就可以生成16个固定光路的0.5mm的石英微型比色皿,用于230、260和280 nm的测量。

为了方便使用和优化数据质量,NanoQuant板是市场上唯一一种100%无校准的低容量板,在保持可靠性能的同时尽量减少维护时间。这种创新的工具是在你的实验室中进行灵敏度高、可靠和容易的DNA/RNA定量的先决条件。

除了吸光度测量外,NanoQuant板还可用于检测小体积样品中的荧光信号。只需用加入的用于荧光测试的2微升样品(例如Quant IT™Picogreen®dsDNA Assay)到NanoQuant板上,然后就可以使用Spark检测荧光信号。

NanoQuant 和 Spark的结合可以为核酸定量提供终极方案。

荧光 – Fusion 光路

革命性设计带来出色灵敏度和灵活性

Spark的Fusion光路是首个在单次荧光测量中,将单色仪的灵活度与滤光片的灵敏度结合在一起的解决方案。

展示更多

一款卓越的多功能检测器

Spark可以配备滤光片,Tecan最先进的QuadX Monochromators™双光路系统。不同于其它多功能酶标仪,这个设计可以允许客户独立的在滤光片和光栅之间进行选择。

这一独特的功能可用于所有基于荧光的检测模式,包括标准的顶部和底部测量、TRF、FRET、TR-FRET和FP,提供非常低的检测限值。SparkControl软件提供了对系统的轻松控制,可以方便地选择滤光片和光栅。

Closing the gap between flexibility and sensitivity

Spark’s unique ability to combine the flexibility of monochromators with the sensitivity of filters is especially relevant for fluorescence emission or excitation scans. For example, using a filter on the excitation side gives higher instrument sensitivity, significantly improving peak quality.

The image shows a comparison of excitation and emission scans for standard fluorophore label (A), Alexa Fluor® 555 (B) and europium (C), revealing that using monochromators on both sides only detects ~25 % of the signal compared to using filters on the fixed wavelength side. This allows Spark’s Fusion Optics to dramatically increase the peak quality of the fluorescence spectra, even for very low signals.

Key features for fluorescence

  • Automated Z-focusing – optimal top and bottom focusing in every well, independent of plate type and format
  • Flexible bandwidth selection – from 5 to 50 nm for an optimal balance between specificity and sensitivity
  • Multiple dichroic mirrors – to maximize instrument sensitivity in combination with filters or monochromators
  • Optimal Read function – for bottom reading fluorescence, guaranteeing signal recording from all cells in the well, ideal for detection of GFP signals
  • Well scanning – high density well scanning generates a low resolution fluorescence image of the well
  • Spectra Viewer – software tool for improving excitation and emission settings of your assay
  • 3D scanning – accelerates assay development by providing simultaneous excitation and emission scans, helping to quickly and easily identify changes in the spectral properties of fluorescent probes or characterize unknown samples

发光光路

高灵敏度设计

Spark的发光模块可为 96孔、384孔和1,536孔的微光、闪烁和多色发光应用提供更高的灵敏度。前沿的发光光路设计,可以在保持灵敏度的同时记录光谱,让您获得出色的检测性能,同时又可为未来的发光应用未雨绸缪。

展示更多

优化光学=最佳结果

Optimized optics = optimal results

Spark采用针对每种板格式(96、384和1536孔)优化的发光纤维,确保孔之间的最小信号串扰。该光路通过一个创新的滤光片轮引导,该滤光片由多个衰减滤光片组成——将高信号减少多达1000倍——以及38个用户可选择的彩色滤光片,几乎可以实现任何多色发光测量。产生的信号由光电倍增管(PMT)检测,该光电倍增管以其最灵敏的模式工作:光子计数。

这种光学元件的独特组合确保了弱发光信号的最大灵敏度,并允许高信号的衰减。其检测范围高达10^9位于行业领先水平,同时还有对辉光和闪光有极低的检测下限。

Emission spectra of Renilla (RR) and firefly (FF) luciferases recorded with the Spark

用多色发光优化你的实验

大多数孔板检测器采用单光栅荧光发射器进行发光扫描,这将导致由于衰减导致的不可接受的灵敏度下降和较差的结果。

为了克服这一限制,Spark使用了一种基于19对短通和长通滤光片的独特滤波技术。只需点击几下,您就可以为多色发光测量或光谱扫描选择所需的波长和带宽。这使得Spark成为了一个面向未来的多重分析检测系统(如Chroma-Glo™) 、BRET应用(包括NanoBRET™)和发光检测器。

Alpha 酶标仪

Alpha实验技术的完美性能需要高质量的仪器。Spark将一个高功率激光光源与一个创新的滤光片和专用的光子计数PMT相结合,用于超灵敏Alpha实验。

Spark配备了独特的红外温度传感器,能够在测量过程中进行每一个孔的温度校正,克服了众所周知的Alpha实验的挑战。这都得力于Spark的Te Cool™模块,用于控制和提供稳定的温度,甚至低于环境温度,让您完全控制这个关键的实验影响因素。

这些功能确保Spark为AlphaScreen®、AlphaLISA®和AlphaPlex®实验提供无与伦比的性能,以及潜在的未来Alpha应用。

自动化细胞成像

实现细胞计数、活性分析和活细胞成像

在多功能酶标仪之中直接内置简单、高性价比的细胞成像功能。Spark细胞成像模块包括一个LED 明场发光装置、一个4x物镜、一个CMOS 130万像素摄像机和一个牢固的激光自动对焦系统,可提供堪比自动化显微镜的性能。对于希望进入这一激动人心的应用领域的用户,该系统可提供经济的解决方案。

Cell counting and viability

Cell counting and cell viability assessment of trypsinized cells is a daily task in any cell culture lab. Spark’s cell imaging module offers automated label-free cell counting and trypan blue-based cell viability analysis with an easy-to-use, disposable Cell Chip. Each chip has two sample chambers which can accommodate 10 μl of cell suspension, and four Cell Chips can be loaded onto the Cell Chip adapter, allowing eight samples to be analyzed in less than two minutes.

This user-friendly solution offers: 

  • High throughput, label-free cell counting, even at low cell concentrations
  • One-click live/dead analysis
  • High precision replicate processing for multiple samples
  • Fast and simple mean value calculations, greater accuracy and more precise data

Histogram view to enable adjustment of the analysis based on cell size for the study of sub-populations, eg. for cell swelling assessments

Live cell imaging and confluence

In general, you don’t know how many cells have adhered to the bottom of a microplate well, or even grown, over a certain period of time. Determination of cell confluence and estimation of cell numbers are therefore important for reproducible assay results and interpretation of experimental data.

With Spark’s cell imaging module, you can automatically assess the precise confluence – from 10-90 % –  giving you a new level of data quality in your assays.

Key applications:

  • Visual quality control of cells in microplates – an automated microscope in your reader
  • Label-free cell proliferation – detect cell growth in real time, without manual interference
  • Better assay consistency – always start your assay at the same confluence level, increasing the reproducibility of your cell-based assays
  • Signal normalization – use confluence data to normalize your cell-based signals to the cell mass in your well
  • Quality control – prove the optical quality of your microplate using confluence assessments
  • Wound healing studies– perform semi-automated cell migration and wound healing assays with comparable performance to a dedicated imaging device
  • Single cell cloning – combine automated image acquisition with semi-automated image analysis to verify monoclonality

自动化孵育器

Spark配备了精确的温度控制,使您的微孔板均匀加热。为了确保温度分布均匀,微孔板室与光学元件热隔离,确保稳定精确的温度调节。

Spark通过将CO2/O2控制,还增加另一层的环境控制参数。集成气体控制模块(GCM™)提供从0.04%到10%(体积)的二氧化碳调节,和从0.1%到21%(体积)的氧气调节,为您的细胞创造理想的环境。在长期的动力学研究中,二氧化碳的调节维持了细胞的健康,而氧气的控制使你能够培养微需氧生物或模拟生理条件的正确环境。

对于生产良好的细菌或酵母生长曲线也需要有效的振荡。基于多年的经验和在微孔板中培养细胞系的知识,Spark也专门为微生物的长期振动和孵化进行了优化设计。

易上手的SparkControl软件可以直接控制这些功能,为您的活细胞分析提供最佳条件。

湿度控制-防止边缘效应

95%或更高水平的湿度调节是保持细胞活力和生长良好的另一个关键因素,在长期分析过程中,减少蒸发对于保持恒定浓度至关重要。Spark的 Humidity Cassette 是专门为SBS格式的孔板设计用来减少蒸发,且经济有效的解决方案。该专利工具包括一个填充装置,和配合我们独特的盖子升降机的专用盖子,这都可以用来提供被动的湿度控制。只需在填充装置中添加ddH2O,就可以保持湿润的空气。

板盖升降装置

Spark为您提供了一种新型的自动化系统—集成的盖子开关功能。这种功能创造了新的工作流程可能性,降低了样品污染的风险,并帮助您为长期动力学分析建立了理想的环境。无论您是想在不需要人工干预的情况下分配化合物,还是在不包含蒸发保护的情况下保持最佳环境条件,Spark都是完成这项任务的最佳选择。

为科学家设计的软件

SparkControl将自动化的可以进行动力学调节的长期动力学实验、远程操作和开放动力学等高级功能结合起来,为复杂的实验提供了一种无需手工操作的解决方案。

许多活细胞动力学实验需要特定的操作,例如,一旦达到某个信号水平或OD值,就需要添加化合物。而配有手动控制的多功能酶标仪会使这个实验变得十分繁琐或容易出错。SparkControl的动态调节功能,在无盖或有盖的微板中都能允许您在控制孔中达到预定信号后,对系统进行编程,以自动执行所需的操作,适用于几乎任何您可以想到的分析工作流程。

SparkControl的远程控制功能允许您从实验室外监控或操作仪器。这使您无需坐在Spark前数小时,即可进行完整的系统控制;只要您连接到互联网,就可以连接到您的实验。

多模式检测器经常被不同的用户用于多个应用程序。长期的活细胞动力学分析可以占用该检测器一整天,限制整个实验室的。SparkControl提供了一个有效的解决方案:开放式动力学。此功能允许您暂停和恢复动力学实验,以便在长期研究中执行其他测量。这为其他用户提供了使用的可能性,消除了共享实验室设备的一个主要瓶颈,同时又不影响您有价值的研究。

Te-Cool – 真正的温度稳定性

整体温度控制 - 即便在低于环境温度的情况下

一致的温度是确保获得可靠结果的先决条件。Spark是首款内置冷却功能的多功能酶标仪,将整体温度控制在18到42 °C之间。

展示更多

不是所以的生物学反应都在37°C

并不是所有的生物学反应都发生在37°C。例如斑马鱼幼虫需要25°C,昆虫细胞(Sf9)需要22°C。常见的多功能检测器只能加热孔板,并通常会有高于室温2~5°C的偏移。这种传统的方法就丢失了灵活性,而且实验的条件也不是最优的,因此还会导致产生不可靠或不可用的数据。这种功能的缺乏也限制了你研究某些生物体或应用的能力。

Exemplary luminescent kinase assay, where the activity of a glow luciferase was measured at different temperatures. The luminescent signal increased approximately 10 % per 1 °C increase in temperature.

温度对发光的影响

温度对使用非哺乳动物生物的酶进行生化分析起着至关重要的作用。例如,生物发光分析系统的最佳温度为20到25°C之间。这些分析测试通常对温度敏感,即使温度升高1°C,发光输出也会增加10%。因此,无法在这个临界范围内稳定控制温度的光度计或多功能检测器将产生不可重现的数据。 Spark是唯一一个可以减轻温度对发光分析实验影响的检测器,为您的有价值的研究提供更高质量的数据

快速冷却

支持多用户的检测仪就需要多种的实验条件。微孔板检测器的一个主要瓶颈,就是需要等待仪器到达所需的温度。加热测量室很容易,但是如果是需要冷却呢?

一般情况下,一个被动降温的检测仪通常需要60分钟才能使37°C冷却到室温,这个时间会耗费您宝贵的时间还会打乱您繁忙的日程安排。想象一下,在多用户的实验室里,光光是降低冷却的时间就能有效避免项目延迟和效率的降低。

Prioritize your valuable resources

Researchers in every lab are constantly being pushed and pulled to make the next discovery on limited assets. Whether the constraint is driven by budget or time, we have all felt the burden.

Spark brings together a unique set of features intended to ease this strain and create new workflow possibilities for your laboratory, reducing hands-on time while producing high quality data for each and every sample.

Whether you are looking to design long-term experiments that work around your schedule, attempting to shrink sample volumes to reduce costs, or trying gain access to multiple instruments on a tight budget, Spark gives you control over your priorities. 

Eliminate data variability at the source

As scientists, we consider ourselves data-driven. Whether your research is centered in academia or industry, your next discovery will rely on your data. The ability to generate reliable, reproducible and high quality data should be a prerequisite for all laboratory instruments.

Every time you run an experiment you invariably introduce some level of error that impacts your results. Variability is hard to avoid, whether it is transferring your cell-based assay between instruments or manually assessing confluence. Whether the errors are human subjectivity, environmental factors or contamination, you are influencing your results. Completely eliminating this variability isn’t realistic, so you are forced to make concessions. But isn’t your data too important to compromise?

Spark is designed to address almost every detail of the most demanding assays and applications, delivering technologies that seamlessly work together to allow you to generate accurate and consistent data, each and every day.

Application Guide

LEARN – SELECT – MEASURE

Application Notes

A lot of research is devoted to the search for new compounds with bioactivity against bacteria. However, it is important to distinguish between antimicrobial activity and antibiofilm activity. Antimicrobial activity affects bacterial growth, and reduced growth can simultaneously result in a decrease in biofilm production. Antibiofilm activity only affects the formation of biofilms. Therefore, the use of antimicrobial compounds at concentrations that are not bactericidal against all susceptible bacteria often leads to the emergence of resistant strains. In contrast, antibiofilm compounds do not affect bacterial growth, and so do not generate the same opportunities for resistance to develop. This Application Note describes the SIMBA – SIMultaneous detection of antiMicrobial and anti-Biofilm Activity – method using the Spark multimode reader to generate OD600 growth curves for S. Infantis in a 96-well microplate over a 20- hour period, allowing the parallel determination of antimicrobial and antibiofilm activities of selected cold water fungal extracts.

Environmental pathogens are microorganisms that inhabit our surroundings, living outside of a human host for a large portion of their lifecycle. Many of these micro-organisms cause severe pathogenic conditions in plants and are often the reason behind significant crop failures that in turn lead to economic damage. Environmental pathogens can also cause diseases in humans and, in some cases, lead to severe infections that are difficult to treat. There is therefore a need for accurate methods to study these pathogens, and a common way to do that is through turbidimetric measurements. The aim of the current study was to investigate how bacterial growth is affected by temperature, using two different environmental pathogens – the rod-shaped Gram-negative Pseudomonas syringae and Erwinia amylovora.

Bioluminescence resonance energy transfer (BRET) is a well-established detection technology for the investigation of protein-protein interactions in living cells. The latest-generation BRET assay, NanoBRET™, employs an extremely bright NanoLuc® luciferase and a long-wavelength acceptor fluorophore, resulting in a markedly improved detection sensitivity and a higher dynamic range. This application note describes the implementation of NanoBRET technology on the Spark multimode reader, using the NanoBRET Target Engagement Intracellular HDAC Assay.

The novel ValitaTITER assay provides a very accurate and cost-effective solution for the detection and quantification of IgG and Fc-containing proteins directly in cell culture supernatants In this application note, we show the optimal protocol for performing IgG/Fc-protein quantification using ValitaTITER assay kits with the Spark and the Infinite 200 PRO multimode plate readers.

Temperature is a major factor affecting the rate and dynamics of biochemical reactions. The Spark® multimode reader’s ingenious Te-Cool™ module permits measurements even below ambient temperature, thereby limiting the effects of temperature increases in the laboratory on the dynamics of assays. It helps to stabilize temperature-dependent assays and makes the results more reproducible and reliable.

The Optimal Read function for fluorescence bottom measurements is designed to enable uniform well illumination during excitation while and whole-well emission for 6-to 384-well plates. Performing multiple measurements on spatially separated spots arrayed across each well ensures that even heterogeneous cell layers can be effectively and reproducibly analyzed. This application note shows that the Optimal Read function produces the most reliable results for the analysis of adherent cell types, giving the highest well-to-well uniformity and best sensitivity for cell-based applications.

Cell counting, viability analysis and determination of size distribution are routinely performed by researchers across multiple disciplines, from standard cell passaging for downstream experiments to using insect cells infected with baculovirus to produce recombinant proteins, or determining the differentiation capacity of stem cells. Tecan’s Spark multimode reader has an integrated, bright field cell imaging module. This patent-pending system enables label-free cell counting, size distribution determination and trypan blue-based cell viability analysis with an easy-to-use, disposable Cell Chip™. In this study, the analysis of cell concentration, cell viability and size distribution for the determination of the optimal protein production rate in recombinant Sf21 cell cultures is presented.

HTRF is a time-resolved fluorescence resonance energy transfer (TR-FRET)-based assay system from Perkin Elmer cisbio, and is popular for the analysis of various molecular interactions and binding studies. HTRF assays place high sensitivity demands on multimode readers. The Spark offers a number of features to meet these demands and to ensure optimal assay performance, including Tecan’s unique Fusion Optics which combine the sensitivity of filters and the flexibility of monochromators (MCRs) in one instrument. In addition to entirely filter- or MCR-based measurements, a combination of the two can be used simultaneously within one measurement. Automated Z-position optimization and an integrated dichroic mirror that is perfectly suited to HTRF measurements further increase the Spark’s outstanding sensitivity. This application note describes the validation of the Spark reader, equipped with standard fluorescence optics, for HTRF measurements.

This application note describes the successful implementation of AlphaScreen on the Spark multimode reader, as well as the performance of the instrument with regards to measurement sensitivity, uniformity and typical read times.

This application note describes the implementation of the AlphaScreen technology on the Spark multimode reader and the detection of tyrosine kinase activity using the AlphaScreen P-Tyr-100 Assay Kit.

This application note describes the implementation of the AlphaLISA technology on the Spark multimode reader and its use for the detection of human immunoglobulin G (IgG) using the AlphaLISA IgG Assay Kit.

Tecan’s Spark multimode microplate reader was used to identify metabolic changes during the differentiation of human mesenchymal stem cells and to assess and quantify cell viability, cytotoxicity and apoptosis, using several well-established and reliable cell-based assays developed by PromoCell.

For many cell biology applications – such as the identification and separation of high expression clones or knock-down candidates, and small-scale antibody or protein production – it is important to ensure that cell lines originates from a single cell, i.e. they are monoclonal. This can be a major bottleneck, especially for academic laboratories, as dedicated automated microscopy systems are both very expensive and complex to operate, meaning verification of monoclonality is often performed by manual microscopy.

Technical Notes

Fast and reliable nucleic acid quantification and purity checks are important daily routine applications for many laboratories, driven by the widespread use of next generation sequencing and other high throughput nucleic acid analysis techniques. Many methods require rapid, accurate analysis of small sample volumes to keep pace with downstream processes.This technical note shows the optimized Spark measurement settings, as well as comparative results, for the commonly used fluorescence-based DNA quantification assays evaluated in this study.

This technical note describes a method to perform UV[1]based protein quantification using the Spark multimode reader and the low volume NanoQuant Plate with the one-click SparkControl application. It shows comparative data for UV absorbance-based protein quantification in microplates and the gold standard for dye-based methods, the Pierce™ BCA assay. The study results can be used as a guideline to help scientists choose the right method for their specific application.

Evaporation has a huge impact on the performance of both biochemical and cell-based assays, changing reagent, component and metabolite concentrations to alter reaction kinetics and cell physiology. It is therefore crucial to keep the consistency throughout the whole plate to allow comparison of data between wells during life sciences experiments. This technical note highlights the benefits of using the Tecan’s Humidity Cassette in combination with the Spark. The Humidity Cassette can minimize the impact of edge effects in microplates under certain conditions. It provides better uniformity and delivers more reliable data for long-term studies.

Spark’s fluorescence module is available with a choice of filters, monochromators or Fusion Optics – a novel combination of both monochromators and filters. The Fusion Optics module combines the flexibility of monochromators with the sensitivity of filters in a single device, and even within individual measurements. In addition to this enormous flexibility, users can choose either a standard or an enhanced fluorescence module for their Spark multimode reader. The standard fluorescence module is tailored to basic applications, with an exceptionally good performance in the green wavelength range. The enhanced optics module is designed for higher throughput applications in 384- and 1,536-well plates, and offers better performance in the red and blue wavelength range, as well as for high throughput screening (HTS) assays, including TR-FRET and FP.This technical note describes the differences in the sensitivity-to-speed ratio of the standard and enhanced modules in 96- and 384-well plates for measurements using fluorescein (green) and Alexa Fluor® 555 (red).

Monitoring growth of prokaryotic cells and yeast is an important tool in life sciences, as well as in the food industry. This technical note demonstrates the Spark reader’s suitability for the generation of growth curves in the commonly used 24- and 96-well plate formats for three different, well-established bacterial strains, Escherichia coli, Listeria innocua and Staphylococcus capitis. It describes the established methods to generate OD 600 growth curves of all three bacterial strains in 24- and 96-well plates over a period of 8 hours. The influence of important instrument settings, such as shaking, are considered and discussed.

This technical note outlines the use of the Spark reader in combination with the ValitaTITER assay for the quantification of IgG. It offers a comparison of the use of the instrument’s standard and enhanced fluorescence optics, and discusses the optimization of flash number to produce high quality, reproducible data while minimizing read times.

It offers a comparison of the use of the instrument’s standard and enhanced fluorescence optics, and discusses the optimization of flash number to produce high quality, reproducible data while minimizing read times.

Spark-Stack is a compact, versatile and field-upgradeable microplate stacker for the Spark® multimode reader. It offers walkaway automation and enhances the productivity in the lab by helping to automate typical workflow steps – including plate loading, unloading and restacking of 6-1536-well microplates. Spark-Stack can be equipped with dark covers to protect light-sensitive assays inside the plate magazines, such as Alpha technology-based assays and fluorophore-transfected cells.

The one-click Live Viewer software application turns the Spark microplate reader into a microscope. It enables easy and straightforward visual quality checks of cells in microplate wells or in Tecan's proprietary Cell Chip™, allowing researchers to automatically acquire and instantly view images of their cell samples immediately before the measurement is started.

The Spark reader is equipped with Tecan's unique Fusion Optics, which combine the benefits of filters and MCRs in a single multimode reader. The Spark can be equipped with filters, Quad4 Monochromators or a combination of both using the ingenious Spark Fusion Optics.

The new Spark multimode microplate reader is equipped with patent-pending High Speed Monochromators (HSM) enabling highly accurate, reproducible and ultra-fast absorbance measurements. This unique optical system offers an enhanced measurement range from 200 to 1,000 nm, ensuring optimal performance across the full range, particularly for absorbance measurements in the deep UV range, such as A260/A230 nucleic acid purity checks. The Spark reader is also suitable for measurements of low volume samples in both absorbance and fluorescence modes using the patented NanoQuant plate.

With the Spark‘s luminescence module, users can perform high sensitivity flash and glow luminescence measurements. For optimized signal detection of very high and low signals within one experiment, optical density (OD) filters help to attenuate strong signals in the range from OD1 to OD3, thereby avoiding ‘over’ readings. This enables users to detect luminescence signals with a dynamic range of more than 9 orders of magnitude.Multicolor luminescence assays with up to five different luciferases, as well as luminescence spectral scanning (eg. of luminescent proteins) can be easily set - using an innovative filter-based approach, users can select any wavelength between 398 nm and 653 nm, with a step size of 15 nm and a 25 nm bandwidth.

This technical note describes the optimized test set-ups, instrument settings and statistical equations that were used to determine the maximum instrument sensitivity of the Spark multimode reader for flash and glow luminescence.

This technical note describes the optimized test set-ups, instrument settings and statistical equations that were used to determine the best possible detection limit for standard fluorophore label in fluorescence intensity top reading mode (FI top).

The detection limit for the far red fluorescent dye Alexa Fluor 647 – which has a fluorescence spectrum comparable to Cy5 – was determined, operating each instrument in MCR mode.

This technical note describes the implementation of the DLR Assay System on Tecan’s next generation high-end multimode reader platform Spark. It can perform high sensitivity flash and glow luminescence measurements with a dynamic range of more than nine orders of magnitude. In addition, its enhanced luminescence module can measure multicolor assays with up to five different luciferases, as well as offering spectral scanning of luminescent substances.

This Technical Note describes the functions and benefits of the Spark multimode microplate reader and cell imaging module, as well as the SparkControl software and its dedicated Cell Counting and Cell Viability Application.

This technical note compares the performance of the Spark’s cell counting module with (i) manual cell counting using C-Chip™ disposable hemocytometers and a standard microscope, (ii) a comparably priced, imaging-based cell counting device (Device A) and (iii) a high performance cell imager with counting capabilities (Device B).

The Transcreener® ADP2 TR-FRET Red Assay is a competitive immunoassay for ADP with a far-red, time-resolved fluorescence-resonance-energy-transfer (TR-FRET) read-out. It is intended for the detection adenosine diphosphate (ADP) production by any kinase or ATPase, and has been developed specifically for high-throughput screening applications. The Spark was tested for its capacity to measure the Transcreener ADP2 TR-FRET Red Assay using the four different combinations of the Fusion Optics.

The Transcreener ADP2 FP assay is a competitive FP assay based on the detection of ADP and is therefore compatible with any enzyme class that produces ADP, including protein, lipid, and carbohydrate kinases, ATPases, DNA helicases, carboxylases and glutamine synthetase. This technical note describes the instrument settings for the Transcreener ADP2 FP assay on Tecan’s Spark multimode microplate reader.

The Host-Microbiota Interactions Lab at the Wellcome Sanger Institute uses high throughput anaerobic microbiology, genomic and metagenomic approaches to explore the relationship between humans and their microbiome – the community of microorganisms that live on and in us. HMIL has developed techniques to culture strict anaerobic gut bacteria at scale and built an extensive culture collection for phenotypic profiling. To phenotypically screen this culture collection, HMIL uses a Spark multimode reader equipped with an integrated stacker module – the Spark-Stack™ – for automated and high throughput plate processing, which is housed in a Whitley A135 HEPA Anaerobic Workstation. This allows the generation of bacterial growth curves cultured in multiple microplates under stringent anaerobic conditions, i.e. at 0 % O2 using a dedicated and pre-optimized gas mix (80 % N2 , 10 % CO2 and 10 % H2 ). Here, we describe accurate profiling of the growth kinetics of strict anaerobic gut bacteria.

Cell-based assays are very popular in life sciences research, as they represent an in vitro system which offers results comparable to in vivo systems. However, this improved biological relevance is counterbalanced by the complexity of working with a living organism. Cell-based assays therefore require special precautions and care when planning and conducting experiments
