SYTO™ 40 Blue Fluorescent Nucleic Acid Stain - 5 mM Solution in DMSO

The cell-permeant SYTO 40 blue fluorescent nucleic acid stain exhibits bright, blue fluorescence upon binding to nucleic acids. Because the staining pattern of the SYTO dyes in live cells may vary from one cell type to another, we offer the SYTO Blue Fluorescent Nucleic Acid Stain Sampler Kit (Cat. No. S-11350) to enable researchers to find the dye that works best for a particular application.

Any physiological buffer between pH 7.0–8.0, including PBS, can be used to dilute the SYTO dyes for the staining solution.
