Highly purified human alpha-1-antitrypsin (phenotype MM) was obtained by an original method of preparative electrophoresis. The criteria of homogeneity were assured by one arc in crossed immunoelectrophoresis and one band on polyacrylamide gel. A unique N-terminal amino acid (pyroglutamic acid) and a unique C-terminal residue (lysine) were identified. Determined by gel electrophoresis, its molecular weight was 47,000 daltons.
