The cell-permeant SYTO 59 red fluorescent nucleic acid stain exhibits bright, red fluorescence upon binding to nucleic acids. Because the staining pattern of the SYTO dyes in live cells may vary between cell types, we offer the SYTO Red Fluorescent Nucleic Acid Stain Sampler Kit (Cat. No. S-11340) to enable researchers to find the most appropriate red-fluorescent SYTO stain for their system.
Any physiological buffer between pH 7.0–8.0, including PBS, can be used to dilute the SYTO dyes for the staining solution.
