ApexBlue™ Quick Cell Viability Fluorometric Assay Kit

Resazurin is a blue redox dye with weak fluorescent. When reduction by viable metabolically active cells, the dye becomes pink colored and highly red fluorescent.

 ApexBlue™ Quick Cell Viability Fluorometric Assay Kit provides the easiest and most sensitive way for quantification of cell proliferation and viability. The metabolically active cells reduce blue resazurin into pink colored resorufin, which has high fluorescent (Ex = 530-570 nm; Em = 590-620 nm) and can be easily measured. The assay is very simple and only simply add the reagent to cell culture, incubate and read the fluorescence intensity.
