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. 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 …
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 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.
