DAPI

Catalog No.: A24944
DNA Dye
DAPI (4',6-Diamidino-2-phenylindole) is a fluorescent DNA dye that selectively binds to the AT base pairs in the minor groove of double-stranded DNA, enhancing fluorescence intensity approximately 20-fold upon binding. This property makes DAPI suitable for applications in fluorescence microscopy, allowing for quantification of DNA based on fluorescence intensity. Additionally, DAPI's ability to penetrate intact cell membranes enables its use in staining both live and fixed cells. DAPI also acts as an inhibitor of acid-sensing ion channel 3 (ASIC3), potentially contributing to research in chronic pain treatment (Ex/Em = 356/451 nm).
