[Characterization of various digestive enzyme activities of Palaemon serratus Pennant (Crustacea, Decapoda) after polyacrylamide gradient gel electrophoresis].

Soluble proteins of hepatopancreatic, extracts of Palaemon serratus (Crustacea, Deapoda) are separated by polyacrylamide gradient gel electoresis. The characterisation of the enzymatic activities is carried out directly on the polyacrylamide gel. The zymogram includes the following activities: acid and alcalin phosphatses, phosphamidase, alpha-glucosidase, beta-glucosaminidase, beta-glucuronidase and twenty bands with esterasic activities. The molecular weights are indicated.
