PURPOSE: To make response rate of enzymatic reaction high and to stabilize enzymatic activity even by continuous use of many times, by using a specific polymer as a carrier for an immobilized enzyme to be used for quantitative analysis of urea nitrogen in liquid, uric acid, etc. n CONSTITUTION: In an immobilized enzyme to be used for quantitative analysis of urea nitrogen, uric acid or creatinine contained in liquid, urease, uricase or creatinine deaminase is used as an enzyme and a water-insoluble amino group-containing polyacrylonitrile polymer or its derivative is used as a carrier for immobilizing it. It is preferably in a fibrous state. n COPYRIGHT: (C)1986,JPO&Japio |
