The SYTO Blue Fluorescent Nucleic Acid Stain Sampler Kit contains a collection of cell-permeant, blue-fluorescent SYTO nucleic acid stains (SYTO dyes 40, 41, 42, 45). Because the dyes may demonstrate different staining behaviors with various tissues and cells, it may be necessary to test the dyes to find the optimal dye for a specific application. The kit contains 50 μL of each SYTO dye.

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