But what exactly is the red spectrum telling us? I read that the red spectrum can be …
NettetHoechst 33342 nucleic acid stain is a popular cell-permeant nuclear counterstain that emits blue fluorescence when bound to dsDNA. This dye is often used to distinguish condensed pycnotic nuclei in apoptotic cells and for cell cycle studies in combination with BrdU. It is also available in solution (H-3570). NettetHoechst 33342 is a well-characterized blue-emitting fluorescent compound widely utilized for nuclear staining. Hoechst 33342 permeates cell membranes and binds to the minor groove of A/T-rich dsDNA sequences, thus preferentially staining nuclei (Figure 1). Fig.1. Hoechst 33342 (in blue) binding dsDNA.

Nettet10. jan. 2024 · Hoechst stains are also cell permeable and can therefore be used in fixed and living cells. They exhibit lower toxicity than DAPI. A membrane-impermeable DNA stain is Propidium-Iodide which is often used to differentiate between living and dead cells in a cell culture because it cannot enter an intact cell. NettetFluorescently labeled nanoparticles are widely used for evaluating their distribution in the biological environment. However, dye leakage can lead to misinterpretations of the nanoparticles’ biodistribution. To better understand the interactions of dyes and nanoparticles and their biological environment, we explored PLGA nanoparticles …
