Hoechst flow cytometry
NettetAs DNA is synthesized during S-phase, cells are found with a DNA content ranging between 2n and 4n. A histogram plot of DNA content against cell numbers gives the classical DNA profile for a proliferating cell culture. UV excitable DNA dyes such as DAPI and Hoechst 33342 are normally excited with a UV laser (350-360nm) for cell cycle … NettetFlow cytometry may be used to determine the level of quiescence or senescence in a cell population. The biological processes involved in quiescence and senescence are different in that senescence has to be …

NettetThe properties of a fluorochrome will depend on its environment. For example, propidium iodide (PI), which is used to stain DNA, is only weakly fluorescent in water; on intercalating with DNA, the fluorescence increases 50 fold due to the hydrophobic environment. Some fluorochromes, such as fluorescein, are sensitive to pH. Nettet3. mai 2024 · This method used Hoechst 33342 to stain the spermatozoa and sorted the X and Y chromosome-bearing spermatozoa using flow cytometry. The sexed sperm are subjected to in vitro fertilization and subsequent artificial insemination in cattle and pigs (Johnson et al., 1999 ). 4.6 Applications of Sexed Semen Sorted by FACS 4.6.1 Cattle
