    Live-or-Dye™ Fixable Viability Staining Kits

    From: $63 Sizes: 50 assays, 200 assaysCatalog #: 32002-T, 32003-T, 32009-T, 32004-T, 32005-T, 32006-T, 32007-T, 32008-T, 32002, 32003, 32009, 32004, 32005, 32006, 32007, - 32008View allHide

    Live-or-Dye™ Fixable Viability Staining Kits are designed for discrimination between live and dead cells during flow cytometry. Live/dead stains are useful probes to include when analyzing cell surface protein expression by flow cytometry, because they allow intracellular fluorescence signal from dead cells with permeable plasma membranes to be excluded from analysis.

    ViaFluor® SE Cell Proliferation Kits use amine-reactive dyes to covalently label the cell cytoplasm, and are used to monitor cell division by flow cytometry. The dyes also can be used to stably label cells to image cell morphology, or to track cell populations in mixed co-culture experiments. The labeling withstands fixation and permeabilization for immunostaining.
