    4',6-Diamidino-2-phenylindole dihydrochloride (solution)

    DNA Stain Others
    DAPI dihydrochloride (4',6-Diamidino-2-phenylindole dihydrochloride) (solution) is a DAPI dye. DAPI is a fluorescent dye that can bind strongly to DNA. DAPI binds to the A/T base pairs in the minor groove of double-stranded DNA (1 DAPI molecule can occupy 3 base pairs), which amplifies the fluorescence intensity by about 20 times. By observing the fluorescence intensity, DNA can be quantified. DAPI can also penetrate intact cell membranes and is often used to stain living and fixed cells .

    4',6-Diamidino-2-phenylindole dihydrochloride

    DNA Stain Others
    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 .

    4',6-Diamidino-2-phenylindole dilactate

    Fluorescent Dye Others
    DAPI (dilactate) is a blue fluorescent dye that preferentially binds dsDNA and binds to minor groove AT clusters. DAPI (dilactate) is combined with dsDNA, and the fluorescence was enhanced about 20-fold. DAPI (dilactate) can be used to identify the cell cycle and specifically stains the nucleus but not the cytoplasm. DAPI (dilactate) form is more soluble in water than DAPI (dihydrochloride) form.
