SYTOX™ Green Nucleic Acid Stain - 5 mM Solution in DMSO

Back to top


SYTOX® Green nucleic acid stain is an excellent green-fluorescent nuclear and chromosome counterstain that is impermeant to live cells, making it a useful indicator of dead cells within a population.

Also available as a room-temperature-stable, ready-to-use solution: NucGreen Dead 488 Ready Probes Reagent.

 Impermeant to live cells
 Excitation/Emission: 504/523 nm
 Use with 488 Argon-ion laser
 Works with mammalian cells and both Gram-positive and Gram-negative bacteria

Simple Viability Determination
SYTOX® Green allows quick determination of cell viability when using flow cytometers, fluorescence microscopes, fluorometers, or fluorescence microplate readers. It will not cross intact membranes, but will easily penetrate compromised membranes characteristic of dead cells. Because it exhibits >500-fold fluorescence enhancement upon binding nucleic acids, briefly incubating dead cells with SYTOX® Green will result in bright green fluorescence with an emission peak of 523 nm when excited by a 488 nm argon-ion laser or any other 450–490 nm source. The exceptional brightness of the signal produced in dead cells makes SYTOX® Green particularly useful for determining viability of not just mammalian cells, but both Gram-positive and Gram-negative bacteria.

Part of the Invitrogen Family of Cell Viability Stains and Assays
SYTOX® stains for dead cells are available in a variety of colors, including red, blue, and orange. Additionally, Invitrogen has incorporated SYTOX® stains into a number of assays for apoptosis, cell viability, and metabolism.
