Invitrogen™ eBioscience™ Fixable Viability Dye eFluor™ 455UV

Can be used to irreversibly label dead cells prior to cryopreservation, fixation and/or permeabilization procedures. Unlike 7-AAD and PI, cells labeled with Fixable Viability Dyes can be washed, fixed, permabilized and stained for intracellular antigens without loss of staining intensity.
