DAPI (hydrochloride) (solution)

DAPI is a fluorescent DNA probe. It forms a fluorescent complex by attaching in the minor groove of adenine and thymine-rich sequences of DNA. DAPI displays excitation/emission maxima of 347/453 nm, respectively. It has been commonly used as a cell viability dye and as a counterstain for DNA and chromosomes in fluorescent microscopy and flow cytometry applications.Formal Name: 2-[4-(aminoiminomethyl)phenyl]-1H-indole-6-carboximidamide, dihydrochloride.
