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.

    Lds-751 is a nucleic acid stain that mainly detects DNA. Lds-751 is a nucleic acid stain that mainly detects DNA. Lds-751 has a high affinity for DNA and fluorescence is enhanced after binding, but the maximum emission wavelength is 670nm. Lds-751 and Thiazole orange can be used for the differentiation of red blood cells, platelets, reticulocytes, and nucleated cells and can be stimulated at 488nm. Studies have shown that LDS-751 binds almost exclusively to mitochondria when incubated with nucleated living cells. After nucleated Acridine Orange (HY-101879) staining and LDS-751 treatment of cells, confocal microscopy revealed almost no co-location of the cells. Staining with Rhodamine 123 (HY-D0816), a dye known to bind polarized mitochondria, was almost identical to the pattern observed with LDS-751.

    Ethidium homodimer
    		≥99.0%
    Ethidium homodimer (EthD-1) is a high-affinity fluorescent nucleic acid dye commonly used to stain mammals, bacteria, yeast, and fungi. Ethidium homodimer binds to DNA or RNA, enhancing fluorescence more than 30 times. The Ethidium homodimer has a strong positive charge, so it cannot cross cell membranes and stain living cells; But the Ethidium homodimer can cross the disordered region of the dead cell membrane to reach the nucleus and embed the DNA double strand to produce red fluorescence. Therefore, Ethidium homodimer is a relatively sensitive nucleic acid stain that can accurately detect nucleic acids in solution or in decomposing cells. Ethidium homodimer binds DNA, Ex/Em=528/617 nm.
