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. WebOct 15, 2015 · Cilia are antenna-like extensions of the plasma membrane found in nearly all cell types. In the retina of the eye, photoreceptors develop unique sensory cilia. Not much was known about the mechanisms underlying the formation and function of photoreceptor cilia, largely because of technical limitations and the specific structural and functional …
