The LIVE/DEAD™ Fixable Violet Dead Cell Stain Kit is used to determine the viability of cells prior to the fixation and permeabilization required for intracellular antibody staining or prior to elimination of biohazardous materials using formaldehyde fixation. This kit has been optimized and validated for use with a violet laser flow cytometer.

  • Stable—dyes are freeze dried in separate vials to maintain stability
  • Robust—staining pattern is the same before and after fixation
  • Low compensation—minimal spectral overlap between other fluorophores

    Unlike products that are sold in solution, the LIVE/DEAD™ Fixable Violet Stain has been conveniently packaged in 40-test vials to help ensure the stability and performance of the dye over time. Amine reactive dyes in solution will lose their effectiveness over a short period of time, therefore it is recommended to completely use the vial once rehydrated. If this is not possible, aliquot the vials in small volumes and store at -80°C, avoiding freeze-thaw cycles.

    Dead cell discriminator stains can lose sensitivity after treatment with fixatives such as formaldehyde or ethanol-based fixation methods required for intracellular phosphorylation studies. The LIVE/DEAD™ Fixable Violet Stain is an amine reactive dye that binds covalently to intracellular and extracellular amines, and the staining pattern is preserved following formaldehyde fixation.

    Low compensation
    The LIVE/DEAD™ Fixable Violet Stain was selected based on its fluorescent properties to minimize compensation between other violet dyes and dyes that excite off of the 488 nm blue laser. The violet-fluorescent reactive dye has an excitation maximum of ~416 nm and is excited well with the 405 nm violet laser, and it has an emission maxima of ~451 nm, so it can be collected in the first channel on most violet laser flow cytometers.

    How it works
    In cells with compromised membranes, the dye reacts with free amines both in the cell interior and on the cell surface, yielding intense fluorescent staining. In viable cells, the dye's reactivity is restricted to the cell-surface amines, resulting in less intense fluorescence. The difference in intensity is typically greater than 50-fold between live and dead cells, allowing for easy discrimination.

    Colors available
    LIVE/DEAD™ Fixable Dead Cell Stains are available in a wide variety of colors to meet your multi-color panel needs.
