SYTO Deep Red Nucleic Acid Stain is cell-permeant dye that specifically stains the nuclei of live, dead, or fixed cells. It can be used in live-cell fluorescent imaging workflows and in fixed cell workflows, including immunocytochemistry, immunohistochemistry, and immunofluorescence experiments. After a brief incubation with the stain, the nuclei of live, dead, or fixed cells fluoresce with a deep red/far red signal that is detectable with a Cy5/deep red standard filter set or laser configuration.

• Cell-permeant dye that stains nuclei of live, dead, or fixed cells
• Detectable with deep red/Cy5 fluorecence filter set, with excitation/emission maxima of 652/669 nm
• Five times greater fluorescent signal when staining dsDNA vs RNA

SYTO Deep Red Nucleic Acid Stain can be mulitplexed with blue, green, orange, red, and near-IR fluorophores when compatible fluorescent filter/laser configurations are used. The stain increases in fluorescence with increasing concentrations of dsDNA. SYTO Deep Red Nucleic Acid Stain displays up to five times more fluorescence when incubated with dsDNA vs RNA, unlike DRAQ or other live-cell deep red nucleic acid stains. It has a bright initial signal and excellent photo stability in a typical imaging experiment. These properties make the stain ideal as a simple and quantitative single-step dead/fixed cell nucleus-labeling dye for use with fluorescence microscopes, fluorimeters, fluorescence microplate readers, and flow cytometers. The stain has been successfully used on live monolayer cells and spheroid cells and as a nuclear counter-stain in immunocytochemistry.
