Invitrogen™ eBioscience™ Fixable Viability Dye eFluor™ 450

Description

• Unlike 7-AAD and propidium iodide, cells labeled with Fixable Viability Dyes can be washed, fixed, permabilized, and stained for intracellular antigens without any loss of staining intensity of the dead cells Thus, using these dyes allows dead cells to be excluded from analysis when intracellular targets are being studied Fixable Viability Dye eFluor™ 450 can be excited by the violet (405 nm) laser line and has a peak excitation of 450 nm that can be detected using a 450/50 band pass filter (equivalent to eFluor™ 450 or Pacific Blue™) For compensation, it is recommended to use a sample of the cells of interest stained with the Fixable Viability Dye If the percentage of dead cells is expected to be less than 5%, then it is recommended to take a small aliquot of cells and heat them at 65°C for 1 minute then immediately place on ice for 1 minute After this treatment, the heat-killed cells can be combined 1:1 with live cells and then stained with the Fixable Viability Dye Fixable Viability Dye eFluor™ 450 is supplied as a pre-diluted solution prepared in high-quality, anhydrous DMSO It should be protected from light and moisture Store at -70°C with dessicant, it may be freeze-thawed up to 20 times Allow vial to equilibrate to room temperature before opening
