Dapi staining protocol bacteria
WebApr 1, 2016 · For the analysis of dying cells, fluorescently labeled Annexin V (Annexin V(FITC)) and propidium iodide (PI) are the most commonly used reagents. Instead of PI, 4',6-diamidino-2-phenylindole (DAPI) can also be used. DAPI is a fluorescent stain that binds strongly to A-T-rich regions in DNA. WebDAPI staining protocol Philip Kerrison and Michael Steinke (Last update: 7 December 2010) 4',6‐diamidino‐2‐phenylindole (DAPI) is a fluorescent DNA stain useful for multiple purposes including,

WebThe presence of bacteria for image analysis or interactions with mammalian cells can be achieved by labelling with FITC, Bis-oxonol dye, DiBAC4 (5) or Hoechst 33342. Viability Bacterial viability can be assessed by commercial kits but DAPI and PI can be used to determine bacterial viability. This can be used in conjunction with Hoechst 33342. WebApr 30, 2024 · Additionally, the effect of DAPI staining on cell viability was investigated by plating stained cells on agar plates. Tests using E. coli showed that 70% of cells remained viable and formed colonies on plates after staining with 10 μg/ml DAPI for 30 min . Higher DAPI concentration (100 μg/ml) was also tested in preliminary experiments, which ...
