DNA Stain

There are several different stains that can be used to visualize and photograph DNA after separation by gel electrophoresis. Molecules of the dye adhere to DNA strands and fluoresce under UV light, showing where the bands are within the gel.

Hoechst stains are part of a family of blue fluorescent dyes used to stain DNA.There are three related Hoechst stains: Hoechst 33258, Hoechst 33342, and Hoechst 34580. The dyes Hoechst 33258 and Hoechst 33342 are the ones most commonly used and they have similar excitation/emission spectra.

    DAPI dihydrochloride
    99.30%
    DAPI dihydrochloride is a DAPI dye. DAPI is a fluorescent dye that binds strongly to DNA. It binds to the AT base pair of the double-stranded DNA minor groove, and one DAPI molecule can occupy three base pair positions. The fluorescence intensity of DAPI molecules bound to double-stranded DNA is increased by about 20 times, and it is commonly observed with fluorescence microscopy, and the amount of DNA can be determined based on the intensity of fluorescence. In addition, because DAPI can pass through intact cell membranes, it can be used to stain both live and fixed cells.
