NettetThe fluorescent dye Hoechst 33,342 was used to visualize the nuclear fragmentation, the characteristic of apoptotic cell death. Typically, MCF-7 cells placed into a 6-well plate at a density of 2×10 5 cells per well were co-incubated with 50 and 100 µM baicalein for 24 h. Nettet2. nov. 2012 · This is a convenient and rapid assay, widely used to identify live and dead cells. Hoechst 33342 is a blue fluorescing dye that stains chromatin DNA. The red fluorescing dye propidium iodide is only permeable to dead cells and cannot enter the intact plasma membrane of living cells.
Nettet6. jul. 2024 · The Hoechst stains offer significantly greater cell permeability than analogous dyes such as DAPI. This means that Hoechst stains, such as Hoechst 33258, are suitable for staining both live and … NettetIn flow cytometry, Hoechst dyes are commonly used with propidium iodide or 7-AAD to discriminate between live and dead cell populations or to investigate the stages …
