WebFor IgG1 modification, naturally occurring cysteine residues can be unmasked by reduction of the four interchain disulfide bonds, revealing up to eight reactive thiol residues. 71 Subsequent reaction with soft electrophiles affords selective bioconjugation at the eight different sites . In some cases, including the approved ADCs Enhertu® and ... WebJul 20, 2016 · The protein bioconjugation is verified by gel electrophoresis and purified by aqueous-based fast protein liquid chromatography in 27% yield of isolated protein material. Structural characterization with MALDI-TOF MS and UV-Vis is then used to verify that the bioconjugation is successful.
