Influence of colipase on the turbidimetric determination of pancreatic lipase catalytic activity.

The influence of colipase on the turbidimetric measurement of the catalytic activity of pure human pancreatic lipase (EC 3.1.1.

Detection of colipase in serum and urine of pancreatitis patients.

Colipase, like other pancreatic proteins, is liberated into the circulation in acute pancreatitis. Its concentration was measured in serum by a turbidimetric and in urine by a titrimetric method. The principle of both assays is based on the reactivation of bile acid inhibited, pure human pancreatic lipase by colipase.

Identification of a non-specific carboxylesterase in human pancreas using vinyl 8-phenyloctanoate as a substrate.

Human pancreatic tissue, pancreatic juice and sera of patients suffering from acute pancreatitis contain a vinyl 8-phenyloctanoate hydrolysing activity which was separated from true pancreatic lipase (EC 3.1.1.

[A glucose dehydrogenase for the determination of glucose concentrations in body fluids (author's transl)].

The isolation of glucose dehydrogenase from Bacillus megaterium M 1286 is outlined. Data on the specificity of the enzyme towards carbohydrates are given. A specific method for glucose determination using this enzyme was developed.
