Vybrant™ Cell Metabolic Assay Kit, with C₁₂-resazurin (Invitrogen™)

In the Vybrant™ Cell Metabolic Assay Kit, nonfluorescent C₁₂-resazurin is reduced to fluorescent C₁₂-resorufin by viable cells; the resulting signal is proportional to the number of cells present. C₁₂-resazurin has better cellular retention than alamarBlue™ dye and can be multiplexed with viability indicators and other biomarkers
