A bright stain in an easy to use, no wash assay
SYTOX™ Green 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™ Green (Fig 1). Because it is non-fluorescent in aqueous media, SYTOX™ Green 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™ Green is designed for flow cytometry using the 488 nm blue laser with emission in the 530/30 BP filter (similar to FITC and GFP). The dye concentration has been optimized for samples with concentrations ranging from 1x10⁴ to 1x10⁶ cells per ml.

SYTOX™ Green Cell Stain has been validated in several cell types including:
•  Jurkat
•  ReH
•  CHO
•  Kg1a
•  3T3
•  HeLa
•  HEK (primary cells)
•  Lysed whole blood

SYTOX™ Green Dead Cell Stain has been tested in several applications including:
•  Apoptosis (Fig 2)
•  Cell cycle
•  Cell proliferation
•  Immunophenotyping assays
