Substrate solution for measuring lipase activity, and method and reagent for measuring lipase activity in sample

摘要

This invention provides a substrate solution for measuring lipase activity, a reagent for measuring lipase activity, and an emulsion solution excellent in storage stability. This invention also provides a method for measuring lipase activity in a sample that enables accurate measurement over a long period of time. This invention further provides a method for improving storage stability of a substrate solution for measuring lipase activity and an emulsion solution. To this end, a substrate solution for measuring lipase activity comprising the emulsion solution comprising micelle particles of 1,2-o-dilauryl-rac-glycero-3-glutaric acid (6′-methylresorufin) ester and side-chain-type nonreactive polyether-modified-type modified silicone oil is used.
