AffiASSAY® Live/Dead Cell Viability Assay Kit (for Mammalian Cells)

Specifications

Description

Quantification of number of live and dead cells is an indispensable tool in cell biology research. BioVision’s Live/Dead Cell Viability Assay Kit, provides a two-color fluorescence method that is based on the simultaneous determination of live and dead cells using two different dyes. Live cell dye easily penetrates intact, live cells and intracellular esterase hydrolyzes the dye to produce a hydrophilic, strongly fluorescent compound that is retained in the cell cytoplasm which can be measured at Ex/Em = 485/530 nm. Dead cell dye enters damaged cell membranes and undergoes a 40-fold enhancement of fluorescence upon binding to nucleic acid, thereby producing a bright red fluorescence (Ex/Em = 495/635 nm) in dead cells. This assay kit provides an easy-to-use, non-radioactive, histological and FACS-based method for measuring cell proliferation, cell viability, chemotaxis, cytotoxicity and apoptosis.
