In the mouse stomach exist two acid proteases separable on the polyacrylamide gel electrophoresis. One of them increases in activity after weaning and is a pepsinogen immunologically related to the pepsinogens of other vertebrates. The other is predominant before weaning and is presumed to be a chymosin-like acid protease.
