Bright Signal—Easily distinguishes dead cells from live cells.
Rapid Staining—Single step, No Wash Assay to assess viability of unfixed cells.
Validation—in Jurkat, ReH, CHO, Kg1a, 3T3, HeLa, HEK (primary cells), and lysed whole blood.
Optimization—Dye concentration has been optimized for use in flow cytometry.
Versatility—Tested in a variety of experimental applications.

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.
