  • Method for assaying urease
    Patent number: 5556760
    Abstract: A method for assaying an enzyme on a targeted solid body surface, including the steps of contacting an end opening of a thin tube with a targeted solid body surface to form a space between the targeted solid body surface and inner wall surface of the thin tube, supplying a substrate solution into the space to bring the substrate solution in contact with the targeted solid body surface, and determining a pH change of the substrate solution in the space by using a pH electrode; and an apparatus therefor.
