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.
