The Complete Amino Acid Sequence of a Mouse x Light Chain


The complete amino acid sequence of the K-chain of the mouse myeloma protein MOPC 21 was established. The protein was reduced and alkylated with iodo[2-14C]acetic acid, and 21 tryptic peptides were isolated, mainly by paper electrophoresis and paper chromatography. Three large tryptic peptides (of 35, 36 and 42 residues), which were difficult to isolate in… (More)
