PerkinElmer Announces New Multilable Plate Reader with Laser Detection

PerkinElmer Inc., a global leader in Health Sciences and Photonics, today announced a new laser detection module to extend the functionality of its versatile EnVision™ Multilabel Plate Reader at LabAutomation 2007, in Palm Springs, California, booth #427.

The TRF LASER option, a compact nitrogen laser unit, provides considerably improved performance for homogeneous time-resolved fluorescence (TRF) assays – a standard platform utilized by academic, biotech and pharmaceutical laboratories for screening biochemical compounds in the drug discovery process.

Enhanced Detection, Less Reagent Consumption, Robust Assays
The EnVision TRF LASER delivers a very short excitation pulse without a tail, resulting in superior signal-to-background noise ratio for optimum Z’ values in homogenous TRF assays (such as LANCE^® Ultra and DELFIA^®). The higher signal/background ratio ensures robust, high-speed assays and requires less reagent consumption in the process, contributing to greater overall laboratory precision and efficiency. The TRF LASER module can be combined with any EnVision option configuration and is fully field-upgradeable.

“The addition of the TRF LASER module integrates a powerful new detection utility into the popular EnVision microplate benchreader, a high-performing platform recognized by lab professionals for its speed, sensitivity and multi-label versatility,” said Mary Duseau, business leader for Detection and Analysis Systems, PerkinElmer Life and Analytical Sciences. “This new option dramatically increases the precision and the measurement speed of TRF assays compared to flash light excitation detection systems.”

EnVision Multilabel Plate Readers are designed to deliver superior performance in every application for every label. The unique modular design provides a scaleable solution for laboratories’ ever-changing application needs and expanding throughput demands. The plate conveyor and stackers have been optimized to achieve maximum possible speed, with parallel functionality as well as fast physical movements. The EnVision instruments are easily integrated into robotic systems and are designed to provide the greatest configuration flexibility, including accepting microplates from 1 to 3456 wells. When combined with the high precision dispenser unit and temperature control, the EnVision can perform fast kinetic measurements, enzyme assays, and numerous other cell-based drug discovery assays.

The EnVision is available in two models: the affordable, single-detector EnVision Xcite Multilabel Plate Reader or the faster, dual-detector EnVision Multilabel Plate Reader. For more information, visit the article webpage.
