    Hoechst 33342 23491-52-3 99.52%
    Hoechst 33342 is a marker dye in Hoechst series. Hoechst is A live nuclear marker dye. Hoechst binds to the grooves in the DNA double strand, which tends to be A/ T-rich DNA strand. Although it binds to all nucleic acids, the A/ T-rich double strand DNA significantly enhances fluorescence intensity Therefore,Hoechst dye can be used for living cell labeling. The fluorescence intensity of Hoechst dye increases with the increase of pH of solution.

    DAPI dihydrochloride 28718-90-3 99.90%
    DAPI (4',6-Diamidino-2-phenylindole) 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. DAPI (Compound 3) is an acid-sensing ion channel 3 (ASIC3) inhibitor. DAPI binds to ASIC3 and blocks the channel function. DAPI can be used in the study of chronic pain treatment (Ex/Em = 356/451 nm).
