title: Determination of alpha1-antitrypsin phenotypes by isoelectric focusing in polyacrylamide gels.
abstract: A method for alpha1-antitrypsin phenotyping is described that uses isoelectric focusing in a pH gradient 3.5 to 5 with polyacrylamide as supporting medium. The method is fast, reproducible, and reliable and offers some advantages over the currently used starch-gel electrophoresis.
