Cyanobacteria. BODIPY® FL, DAPI and CellTracker™ Green BODIPY®.
Collage of images of cyanobacteria stained with various blue- or green-fluorescent probes to complement the natural red autofluorescence from chlorophyll and phycobilisomes. The round cells are Synechocystis sp. (strain PCC 6803), and their membranes were labeled with green-fluorescent BODIPY® FL propionic acid (Cat. no. D2183). The cylindrical cells are Synechococcus sp. (strain PCC 7942), stained with blue-fluorescent DAPI (Cat. no. D1306, D3571, D21490). The filamentous cyanobacteria, Anabaena cylindrica, were labeled with either the green-fluorescent cystosolic stain, CellTracker™ Green BODIPY® (Cat. no. C2102), or with the lipophilic membrane stain BODIPY® FL (Cat. no. D2183). The image was contributed by Mary Sarcina, University College, London.
