ViaKrome Fixable Viability Dyes

The ability to stain dead cells with a viability dye and preserve that staining pattern after fixation is critical for many flow cytometry applications. Exclusion of the dead cells from the data allows cleaner separation and identification of live cell populations. The ViaKrome Fixable Viability product line includes dyes excited by most common lasers and emit in common channels to provide researchers flexibility in panel design.
