WebHoechst 33342 is a fluorescent compound with an excitation peak at 352 nm and an emission peak at 454 nm, giving it a fairly large Stokes' Shift of 102nm. It can be excited … WebExcitation–emission spectra of Hoechst dyes. Both dyes are excited by ultraviolet light at around 350 nm, and both emit blue-cyan fluorescent light around an emission spectrum …
WebThe wavelength of excitation is critical to the total photons of light that the fluorophore will absorb. Fluorescein isothiocyanate (FITC), for example, will absorb light from 400-530 nm but absorbs most efficiently at its peak or excitation maximum of 490 nm wavelength. WebSep 9, 2024 · Introduction The World Health Organization has proposed a 25% reduction in premature cardiovascular disease mortality by 2025 (Roth et al., 2015; Joseph et al., 2024). Myocardial ischemia (MI) is a pathological state that prevents normal cardiac function, and is the most common cause of cardiovascular disease.

Documents reported that R -PE could inhibit cell proliferation in HepG2 and A549 cells, which was significative for cancer therapy.
WebExcitation emission spectrum of Hoechst dye. Both dyes are excited by ultraviolet light at about 350 nm and both emit blue-green fluorescence with a maximum emission spectrum of 461 nm. Unbound dyes have maximum fluorescence emission in the 510-540 nm range. Hoechst stains can be excited with xenon or mercury arc lamps or UV lasers.
