STEMCELL Technologies GloCell™ Fixable Viability Dye Red 780, Size: 500 Tests
GloCell™ Fixable Viability Dye Red 780 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 Red 780 is excited by the red laser at 633 nm and it has a fluorescence emission maximum of 780 nm that can be detected using the 780/60 band pass filter used to detect APC-Cy7.
