LIVE/DEAD® Fixable Blue Dead Cell Stain Kit, for UV excitation

Category: Products & Services > Kits & Assays > Cell Analysis Kits > Cell Viability Kits

The LIVE/DEAD® Fixable Dead Cell Stain Kit employs an amine-reactive fluorescent dye to evaluate mammalian cell viability by flow cytometry. In cells with compromised membranes, the dye reacts with free amines both in the cell interior and on the cell surface, yielding intense fluorescent staining. In viable cells, the dye's reactivity is restricted to the cell-surface amines, resulting in less intense fluorescence. The difference in intensity between the live and dead cell populations is typically greater than 50 fold, and this fluorescence intensity discrimination is completely preserved fol...

LIVE/DEAD® Violet Viability/Vitality Kit, for 405 nm excitation

Category: Products & Services > Kits & Assays > Cell Analysis Kits > Cell Vitality Assay Kits

The LIVE/DEAD® Violet Viability/Vitality Kit provides a two-color fluorescence cell viability and vitality assay that is based on the simultaneous determination of live and dead cells with two probes that measure recognized parameters of cell health: plasma membrane integrity and intracellular esterase activity. Calcein violet AM and aqua-fluorescent reactive dye are optimal dyes for this application; both dyes utilize the violet laser allowing other laser lines to be used for conventional fluorochromes.
