PURPOSE: The titled reagent for raising solubility (dissolution rate and dissolution concentration) of a substrate and measuring sensitivity, comprising an inclusion compound and a solvent except water. n CONSTITUTION: A reagent for measuring activity of N-acetyl-β-D- glucosaminidase[E.C.3.2.1.30] using 2-chloro-4-nitrophenyl-N-acetyl-β-D- glucosaminide as a substrate is obtained by dissolving one or more inclusion compounds selected from 13-crown-6,15-crown-5,12-crown-4, (dimethyl-)α- cyclodextrin, (dimethyl-)β-cyclodextrin, (dimethyl-)γ-cyclodextrin and L-poly-β- cyclodextrin in one or more solvents selected from aliphatic alcohols (e.g., methanol, etc.,) and glycols (e.g., ethylene glycol) except water. n COPYRIGHT: (C)1987,JPO&Japio |
