DAPI

DAPI or 4′,6-diamidino-2-phenylindole, is a fluorescent stain that binds strongly to adenine–thymine-rich regions in DNA. It is used extensively in fluorescence microscopy. As DAPI can pass through an intact cell membrane, it can be used to stain both live and fixed cells. \n \nFeatures \n• This DAPI solution is optimized for use on formalin-fixed, paraffin-embedded tissue sections. \n• The DAPI solution contains an anti-freeze agent so the reagent can be stored at -20 °C without freezing. \n• For convenience the DAPI solution can be removed from the freezer and used immediately without the necessity of thawing. \n• There is no need to aliquot and freeze small portions. \n \nKnown Applications \n• Fluorescence In Situ Hybridization \n• Immunofluorescence with fluorescently labeled antibodies or probes. \n• Fluorescent staining methods. \n \nProduct Description \nThis product is provided ready-to-use, and no further dilution is required.
