GloCell™ Fixable Viability Dye UV 450 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.

GloCell™ Fixable Viability Dye UV 450 is excited by the UV laser at 355 nm and it has a fluorescence emission maximum of 450 nm that can be detected using the 450/50 band pass filter used to detect DAPI, Hoechst 33258, etc.
