Separation of Urinary Isoamylases on Cellulose Acetate

Abstract

A NUMBER of electrophoretic investigations have been carried out on human α-amylases (E.C. 3.2.1.1.). Paper1,2, agar3,4, and polyacrylamide gel5 have been used as media. Norby4 achieved separation of salivary and pancreatic isoamylases from extracts of their tissue of origin on agar gel and also showed that salivary amylolytic activity is itself complex—a point confirmed by Muus and Vnenchak5 recently.
