Les isoamylases du colostrum humain

By means of polyacrylamide gel electrophoresis, four fractions with amylase activity have been shown in human colostrum, pancreatic juice and saliva. Colostrum was fractionated by gel fitration on dextran gel (Sephadex G-100); amylolytic activity was eluted as two peaks well after the elution of the other proteins. Six different amylase-active components could be found in the second peak.
