A novel and comprehensive synthetic approach for the elucidation of protein antigenic structures. Determination of the full antigenic profile of the α-chain of human haemoglobin

Abstract

A comprehensive synthetic approach for the determination of continuous antigenic sites of proteins is presented. This approach consists of the synthesis of a series of consecutive overlapping peptides that, together, systematically represent the entire primary structure of the protein under study. Its application to the alpha-chain of human haemoglobin afforded, for the first time, a full profile of immunochemically active alpha-chain peptides and enabled the localization of all the major continuous antigenic sites of this haemoglobin subunit.
