SYTOX Green nucleic acid stain is an excellent green-fluorescent nuclear and chromosome counterstain that is impermeant to live cells but penetrates the compromised membranes characteristic of dead cells, making it a useful indicator of dead cells within a population.
SYTOX Green stain binds nucleic acids with minimal base selectivity. It exhibits a >500-fold fluorescence enhancement upon binding nucleic acids, with an emission peak of 523 nm when excited by a 488 nm argon-ion laser or any other 450 to 490 nm source.
The exceptional brightness of the signal produced in dead cells makes SYTOX Green stain particularly useful for determining viability of both mammalian and bacterial cells.

SYTOX Green stain products
We offer a range of SYTOX Green stain products for nucleic acid staining and dead cell detection in both flow cytometry and imaging applications. SYTOX Green stain is often included in multiplexed assays for apoptosis or cell viability.
Alternatives to SYTOX Green stain
We also offer a range of nucleic acid stains in simple ReadyProbes format and as components in multiplexed viability assays.
