A nuclear fluorescent stain used for counterstaining paraffin-embedded, formalin-fixed tissue, metaphase chromosomes, or interphase nuclei that have been hybridized with probes detected with Fluorescein, or equivalent stains. Antifade prevents the permanent loss of fluorescence or fluorescent signal quenching due to photobleaching and prolonged exposure to high intensity light sources.
DAPI binds the minor groove of DNA at AT clusters and binds preferentially to ds DNA (Biochemistry 26:4545, 1987).
