A bright stain in an easy-to-use, no-wash assay
SYTOX™ Orange Dead Cell Stain is a cell-impermeant nucleic acid stain. By flow cytometry, dead cells can be easily distinguished from live cells by the increased fluorescent signal due to dsDNA binding of SYTOX™ Orange. Because it is non-fluorescent in aqueous media, SYTOX™ Orange Dead Cell Stain can be applied to cells and visualized with minimal background staining and without an additional wash step.

Validated in flow cytometry
SYTOX™ Orange Dead Cell Stain is designed for flow cytometry using the 488 nm blue laser or 532 nm green laser with emission in the 575/26 BP filter (similar to PE). The dye concentration has been optimized for samples with concentrations ranging from 1x10⁴to 1x10⁶ cells per ml.
