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.

For Research Use Only. Not for use in diagnostic procedures.

    • Frequently asked questions (FAQs)

    How do SYTO dyes bind to DNA?

    The binding mode of SYTO nucleic acid stains is unknown. However, the behavior of these and related nucleic acid dyes suggests the following binding properties:

    1.They appear to contact the solvent (suggested by sensitivity to salt, divalent cations, and in particular, SDS) and thus are likely to have contacts in the grooves.
    2.All SYTO dyes appear to show some base selectivity and are thus likely to have minor groove contacts.
    3.They can be removed from nucleic acid via ethanol precipitation; this characteristic is not shared by ethidium bromide and other intercalators. Likewise, the dyes are not removed from nucleic acid via butanol or chloroform extraction. These extraction methods do remove ethidium bromide from nucleic acid. 4. SYTO binding is not affected by nonionic detergents.
    5. SYTO dyes are not quenched by BrdU, so they do not bind nucleic acids in precisely the same way as Hoechst 33342 and DAPI ((4′,6-diamidino-2-phenylindole).

    SYBR Green I has shown little mutagenicity on frameshift indicator strains, indicating that it isn't likely to strongly intercalate.
