DAPI's blue emission is convenient for microscopists who wish to use multiple fluorescent stains in a single sample. There is some fluorescence overlap between DAPI and green-fluorescent molecules like fluorescein and green fluorescent protein (GFP) but the effect of this is small. See more DAPI (pronounced 'DAPPY', /ˈdæpiː/), 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. … See more This DNA fluorescent probe has been effectively modeled using the time-dependent density functional theory, coupled with the IEF version of the polarizable continuum model See more The Hoechst stains are similar to DAPI in that they are also blue-fluorescent DNA stains which are compatible with both live- and fixed-cell applications, as well as visible using the … See more DAPI was first synthesised in 1971 in the laboratory of Otto Dann as part of a search for drugs to treat trypanosomiasis. Although it was … See more When bound to double-stranded DNA, DAPI has an absorption maximum at a wavelength of 358 nm (ultraviolet) and its emission maximum is at 461 nm (blue). Therefore, for fluorescence microscopy, DAPI is excited with ultraviolet light and is detected through a … See more DAPI can be used for fixed cell staining. The concentration of DAPI needed for live cell staining is generally very high; it is rarely used for live … See more • DNA binding ligand • Hoechst stain • Lexitropsin • Netropsin • Pentamidine See more WebDAPI is a known mutagen and should be handled with care.

WebWhen bound to double-stranded DNA, DAPI absorbs light at 359 nm (ultraviolet light) and emits at 461 nm (fluoresces blue). Bound DAPI has a fluorescence intensity approximately 20 fold higher than that of unbound DAPI. The fluorescence is also directly proportional to the amount of DNA present. WebJul 6, 2024 · 7-AAD is a fluorescent probe and intercalating agent. Like DAPI, it has a strong affinity for binding double stranded DNA. Unlike DAPI which binds to A-T rich regions, 7-AAD selectively binds to G-C rich … fitchburg mass assessor\u0027s database
