MICROPLATE READERS 31


UPDATED microplate reader


ecan’s updated Spark reader combines the benefits of a multimode microplate reader and a bright field imaging system in a compact package. Spark lets users actually see what’s happening to their cells, offering automated cell imaging, confluence measurements, cell counting and viability assessments to simplify cell biology protocols and enable long-term, walkaway experiments. Spark has been developed specifically


T


to address the needs of cell-based workflows, and incorporates a host of features – including precise regulation of temperature, gas partial pressures and humidity – to provide an incubator-like environment and maintain optimal assay conditions. The system’s Live Viewer function turns the user’s microplate reader into an automated microscope at the touch of a button, allowing them to instantly image and photograph defined positions in a microplate well. It offers bright field microscope-like functionality with 4x


magnification and a user- definable focus, providing another way to perform fast and easy quality control of cells before starting an assay. In addition,


Spark’s cell imaging module offers high throughput, label-free cell counting and one-click, trypan blue-based cell viability analysis using disposable Cell Chips. Spark also helps users to generate more reproducible cell-based assay data by allowing them to continuously monitor cell confluence within their microplate, and automatically inject a reagent once a user-defined confluence


level is achieved. Along with with the system’s advanced Fusion Optics – which combines the flexibility of monochromators with the sensitivity of filters – there is a Spark configuration to match all users’ budget and workflow.

NEW READER offers APPLICATION FLEXIBILITY A


zure Biosystems has introduced its Ao absorbance microplate


reader: a stand-alone 96-well plate reader, combining application flexibility and performance in a user-friendly system. An array of 96-well plate-based applications is supported, including ELISAs, nucleic acid quantification, protein quantification, enzyme kinetics, and other colorimetric assays. The Ao was developed with a focus on user requirements for small, easy-to-use laboratory equipment supporting protein, nucleic acid and enzyme research. Focusing on the idea that lab equipment should be intuitive and easy to use, the Ao absorbance reader was designed with a 7in full touchscreen interface, a feature typically restricted to much more expensive systems. Setting up a plate with the Ao can now be done quickly


wavelength detection modes, and a motorised door for easy loading and unloading are all included in the Ao absorbance reader. The software supports pre- processing analysis, concentration determination, interpretation with controls, and kinetic measurement analysis and curves. Lisa Isailovic at Azure

Biosystems says, “Microplate readers are essential instruments in life science research, and we are excited that our Ao microplate reader will expand our support to a broader range of applications with a distinct user-friendly system.


The Ao complements our existing cSeries gel and Western blot imaging systems by providing another tool for protein and nucleic acid research.”
