Description

ViaDye Red Fixable Viability Dye is recommended for dead cell discrimination. It is an amine reactive dye that is impermeable to live cells(1). Dead cells, with their compromised plasma membranes, will preferentially take up the dye. The reactive nature of the dye allows for forming covalent linkages to intracellular proteins. The ViaDye Red Fixable Viability Dye is compatible with fix/perm protocols.

RECOMMENDED USAGE

The ViaDye Red Fixable Viability Dye kit is composed of lyophilized ViaDye Red Fixable Viability Dye and anhydrous DMSO. To reconstitute the dye, bring the kit to room temperature, add 100 µL of DMSO to one vial of the dye, and mix well to ensure that all the dye is in solution. Aliquots of smaller volumes can be made and frozen. It is recommended that the aliquots to not exceed one freeze-thaw cycle.

Note: Cells to be stained with ViaDye Red Fixable Viability Dye need to be washed and resuspended in protein-free PBS prior to staining.

The suggested use of this reagent is 1 µL of ViaDye Red Fixable Viability Dye per 1 million cells in a staining volume of 1000 µL.

For staining in 100 µL volumes, the reconstituted dye can be diluted, 1:10, in PBS immediately before use, and 1 µL of the diluted dye added to the cells. It is recommended that users titrate the reagent to obtain the optimal result for their specific applications, as the optimal concentration varies with different cell types.

 

STAINING PROTOCOL

  • Resuspend cells in protein-free PBS after washing.
  • Add 1uL of ViaDye to cells and vortex well immediately.
  • Incubate for 20 minutes at room temperature, in the dark.
  • Wash once with PBS or with FACS Stain buffer, e.g. 0.2% BSA in PBS, pH 7.4.

Cells are ready for downstream staining or applications.
