Cell Meter™ BX590 fixable viability dye

Discrimination and exclusion of dead cells from live cells allows cleaner separation and identification of cell populations. Cell Meter™ fixable viability dyes are a large family of cell-impermeable fluorescent viability dyes that are optimized to match the major excitation lasers of common flow cytometers, such as 350, 405, 488, 633 and 647 nm. These dyes are impermeant to live cells but permeant to cells with compromised membranes. They irreversibly react with amine- and thiol-containing proteins and other cellular components. Since dead or fixed cells with a compromised membrane more readily react with Cell Meter™ fixable cell stains, thus stain brighter than live cells with an intact membrane, these dyes can be used to assess live vs. dead status of mammalian cells. There are a few factors to be considered when using these dyes, e.g., the titration of each dye to ensure that live cells have minimal to no staining. Cell Meter™ BX590 fixable cell stain is optimized to be excited with the blue laser at 488 nm with emission at 590 nm. Compared to other commercially similar viability dyes, this fixable viability dye is much more robust and stable.

Detection of Jurkat cell viability by Cell Meter™ fixable viability dye. Jurkat cells were treated and stained with Cell Meter™ BX590 (Cat#22514), and then fixed in 3.7% formaldehyde and analyzed by flow cytometry.  The dead cell population (Blue peak)  is easily distinguished from the live cell population (Red peak)  with PE-TexasRed channel, and nearly identical results were obtained before and after fixation.
