    Propidium Iodide 25535-16-4 99.69%
    Propidium Iodide (PI) is a nuclear staining agent that stains DNA. Propidium Iodide is an analogue of ethidine bromide that emits red fluorescence upon embedding in double-stranded DNA. Propidium Iodide cannot pass through living cell membranes, but it can pass through damaged cell membranes to stain the nucleus. Propidium Iodide has a fluorescence wavelength of 493/617 nm and a wavelength of 536/635 nm after Mosaic with DNA. Propidium Iodide is commonly used in the detection of apoptosis (apoptosis) or necrosis (necrosis), and is often used in flow cytometry analysis.

    DAPI dihydrochloride 28718-90-3 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.
