Increasingly popular, total-internal-reflection-fluorescence (TIRF) microscopy systems prefer lasers for excitation because of their spectral purity and brightness. But the use of lasers can restrict other TIRF system components. Clearing these hurdles requires some careful considerations. Learn More

594-nm laser excitation can enhance our ability to analyze cells by flow cytometry. This laser wavelength fills a significant excitation gap between the now common 561-nm line and the red laser sources. Adding this wavelength to the excitation repertoire enables excitation of virtually any visible fluorescent probe for cytometric analysis. Learn More
