摘要：

1. 1. Preliminary investigations have been carried out on the chemical composition of the crystalline style of T. telescopium. 2. 2. Polyacrylamide gradient gel electrophoresis of crystalline style extracts can be used to distinguish between molluscs of the family Potamididae. 3. 3. No difference in structural protein composition was detected along the length of the style but laminarinase and β-glucosidase appear to be secreted into the proximal end of the style only. 4. 4. Laminarinase, fucoidanase, amylase, cellulase, xylanase, β-glucosidase and β-galactosidase activities were found in style extracts. These were further fractionated by ion-exchange chromatography. 5. 5. The level of enzyme activity in the style is correlated with the tidal cycle. © 1979.
