WebPure DAPI-DNA complexes fluorescence is blue-white, while pure DAPI-PolyP com-plexes fluorescence is yellow [1,12]. DAPI-lipid fluo-rescence is white-yellow, week and fades in a few sec-onds [12]. In living cells mixed fluorescence spectra may be observed [13,14]. The green fluorescence of DAPI appears if PolyP are co-localyzed with DNA, or if WebJun 20, 2008 · The presence of polyphosphate granules was determined by fluorescence microscopy. Briefly, cells from a C. pyrenoidosa culture were collected at 24 and 64 h of growth, incubated in solutions of 4, 6-diamidino-2-phenylindole (DAPI; Sigma Inc., 50 μg/ml), mounted on slides and observed using a fluorescence microscope.

WebPolyphosphate (poly-P) is an important metabolite and signaling molecule in prokaryotes and eukaryotes. DAPI (4′,6-diamidino-2-phenylindole), a widely used fluorescent label for DNA, also interacts with polyphosphate. WebOct 1, 2002 · DAPI is a fluorescent reporter that is commonly used to detect DNA but may be used to unambiguously identify polyphosphates, because there is sufficient spectral separation between the... graham norton show channing tatum

WebDAPI is a popular nuclear counterstain for use in multicolor fluorescent techniques. Its blue fluorescence stands out in vivid contrast to green, yellow, or red fluorescent probes of … WebFeb 23, 2015 · The binding of polyP to DAPI shifts the peak DAPI emission wavelength from 475–550 nm under UV-light excitation, and the fluorescence intensity at this shifted wavelength is proportional to the concentration of polyP. Fluorescence measurements were carried out on a FluoroMax-4 spectrofluorometer (Horiba Scientific). WebDAPI is a classic nuclear counterstain for immunofluorescence microscopy, as well as an important component of high-content screening methods requiring cell-based quantitation of DNA content.
