Selective detection of complementarity-determining regions of monoclonal antibody by limiting protease access to the substrate: nano-surface and molecular-orientation limited proteolysis

Abstract

We report a novel method for the selective proteolysis by limiting protease access to the substrate, which we have named nano-surface and molecular-orientation limited (nSMOL) proteolysis. We focus on the identification of the Fab and quantitation of antibodies. This method successfully performed limited proteolysis on the Fab.
