Request InfoMolecular Devices LLCMolecular Devices’ EarlyTox Cell Integrity Kit is a fluorescence-based assay for detecting changes in cell viability based on permeability of outer cell membranes. The kit provides an integrated assay solution when combined with hardware and software for the rapid quantification of cell viability. It is based on two nuclear dyes — EarlyTox Live Red Dye is cell permeable and marks both live and dead cells, while EarlyTox Dead Green Dye is cell impermeable and stains only cells with damaged outer membranes. The Red Dye is detected via Cy5 channel (Ex622/Em645...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics.com March 2024 Issue380-nm Laser ModuleThe IQ1C195(380-210) from Power Technology is a continuous wave high-power 380-nm laser diode module for high-end analytical and scientific applications, such as bioanalysis, fluorescence, and Raman...Promoted Content March 2024 IssueUltra-Precision Microscopy DemoThe Nucleus™ microscopy platform provides a complete set of interchangeable hardware modules and software tools, making it ideal for OEMs and lab managers engaged in fluorescence cellular...Promoted Content February 2024 IssueOEM-Ready Microscope SubsystemsThe Nucleus™ microscopy platform provides a complete set of interchangeable hardware modules and software tools, making it ideal for OEMs and lab managers engaged in fluorescence cellular...Promoted Content November 2023 IssueNucleus™ Automated MicroscopesThe Nucleus™ microscopy platform provides a complete set of interchangeable hardware modules and software tools, making it ideal for OEMs and lab managers engaged in fluorescence cellular...ARTICLESBioPhotonics Nov/Dec 2023 IssueOptical Measurements Combine for Early Metastasis DetectionDiffuse in vivo flow cytometry (DiFC), an optical technique developed at Northeastern University, enables fluorescence detection of tumor cells circulating in the bloodstream.
