N-(2-acetamido)-2-aminoethanesulfonic acid 0-45 serpin family A member 1 Homo sapiens 70-89 3874722-3 1985 I describe a method in which the ultrathin agarose gel contains N-[(carbamoylmethyl)amino]ethanesulfonic acid as a "separator," to flatten the pH gradient and improve separation of the alpha 1-antitrypsin isoforms. N-(2-acetamido)-2-aminoethanesulfonic acid 64-109 serpin family A member 1 Homo sapiens 185-204
