Lipase Assay Kit (LPS)
For the quantitative in vitro determination of Lipase in human serum and plasma.
A lipase test system is a device intended to measure the activity of the enzyme lipase in serum and plasma. Lipase measurements are used in the diagnosis and treatment of diseases of the pancreas such as acute pancreatitis and obstruction of the pancreatic duct.
The chromogenic Lipase substrate 1,2-o-dilaurylracglycero-3-glutaric acid-(6ı-methylre-sorufin) ester is cleaved by the catalytic action of Lipase to form 1,2-odilauryl racglycerol and an unstable intermediate, glutaric acid-(6-methyl resorufin)ester.This decomposes spontaneously in alkaline solution to form glutaric acid and methylresorufin. The lipase activity in the speci-men is proportional to the production of methy-lresorufin in the reaction and can be determined photometrically.
1,2-O-dilauryl-rac-glycero-3-glutar acid-(6 methylresorufin) ester → 1,2-O-dilauryl-rac-glycerol + glutaric acid-(6 methylresorufin) ester → glutaric acid+methylresorufin
