Photoreactive Biotinylation Reagents
Photo-reactive biotinylation reagents are used for biotinylating proteins, peptides, and other molecules for use as molecular probes with streptavidin conjugates. These reagents contain a photoactivatable group that is chemically inert until it is exposed to ultraviolet light and initiate addition reactions with double bonds, insertion into C–H and N–H sites, or subsequent ring expansion to react with a nucleophile (e.g., primary amines).
