WebMar 1, 2011 · The pAcPhe-Fabs were labeled by reaction with hydroxylamine dye and biotin species to produce well-defined, singly conjugated Fabs. We then coupled a hydroxylamine biotin to the pAcPhe-Fab and ... WebIncorporation of pAcPhe is followed by chemoselective reaction of the ketone side chain with a hydroxylamine-functionalized nitroxide to afford the spin-labeled side chain “K1,” and we present two protocols for successful K1 labeling of proteins bearing site-specific pAcPhe. We outline the basic requirements for pAcPhe incorporation and ...
WebNov 1, 2013 · The anti-Her2 IgG containing pAcPhe was then successfully produced by expressing it in a Chinese hamster ovary cell line along with the correct amber suppressor tRNA/aminoacyl-RNA synthetase pair. A linker with an alkoxy-amine was attached to the cytotoxic drug, auristatin F, and then conjugated to the pAcPhe anti-Her2 IgG. WebJan 1, 2015 · The general scheme for incorporation of pAcPhe into E. coli-expressed proteins is outlined in Fig. 2.The technique requires two expression plasmids.
