FIXABLE VIA DYE EF506/780 SMPL PACK，65-2860-40，Affymetrix

Fixable Viability Dye eFluor™ 506 and 780 are viability dyes that can be used to irreversibly label dead cells prior to cryopreservation, fixation and/or permeabilization procedures. 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 Fixable Viability Dyes allows dead cells to be excluded from analysis when intracellular targets are being studied. Fixable Viability Dyes may be used to label cells from all species.

Fixable Viability Dye eFluor™ 506 can be excited by the violet (405 nm) laser line and has a peak emission of 506 nm that can be detected using a 510/50 band pass filter (equivalent to AmCyan). Fixable Viability Dye eFluor™ 780 can be excited by the red (633 nm) laser line and has a peak emission of 780 nm that can be detected using a 780/60 band pass filter (equivalent to APC-eFluor™ 780 or APC-Alexa Fluor™ 750). Please make sure that your instrument is capable of detecting these dyes. 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™ 506 and 780 are supplied as a pre-diluted solutions prepared in high-quality, anhydrous DMSO. They should be protected from light and moisture. Store at less than or equal to -70°C with dessicant. They may be freeze-thawed up to 20 times. Allow vials to equilibrate to room temperature before opening.
