Photoactivatable fluorescent proteins

WebBimane azide is a small blue-fluorescent photoreactive alkyl azide (excitation/emission maxima ~375/458 nm) for photoaffinity labeling of proteins. This reactive fluorophore's small size may reduce the likelihood that the label will interfere with the function of the biomolecule, an important advantage for site-selective probes. WebDec 6, 2024 · Live-cell localization microscopy was enabled by the development of photoactivatable fluorescent proteins (PA-FPs) such as PA-GFP, PAmCherry, mEOS, and other variants [10–12]. In fixed and permeabilized cells, antibody staining permits the use of synthetic dyes which are generally brighter and more photostable than fluorescent proteins.
