Abstract

The reduced and either aminothylated or carboxymethylated H-chain of the monoclonal IgA1 immunoglobulin Tro was digested with trypsin. The tryptic peptides were isolated by gel and ion-exchange chromatography. Because of different methods of alkylation, the cysteine-containing peptides could be obtained in two forms and showed additional overlaps. Sequence studies performed with these fragments elucidated the primary structure of the protein.
