After being separated by gel electrophoresis, DNA can be seen and photographed using a variety of stains. The dye molecules bind to DNA strands and fluoresce when exposed to UV light, revealing the locations of the bands within the gel.
A family of blue fluorescent dyes called Hoechst stains is used to stain DNA.Hoechst 33258, Hoechst 33342, and Hoechst 34580 are three related Hoechst stains. The most popular dyes are Hoechst 33258 and Hoechst 33342, and they have comparable excitation/emission spectra.
