    Abstract: A method for determining the presence of an analyte which is a specific binding pair member in a sample suspected of containing the analyte is described. The method involves: bringing together in an aqueous medium, the sample, an enzyme bound to a first specific binding pair member and an inhibitor for the enzyme bound to a second specific binding pair member wherein each specific binding pair member is capable of binding to the analyte or to a specific binding pair member complementary to the analyte; analyzing the medium for the activity of said enzyme; and relating the activity to the amount of analyte present in the medium. Compositions of matter and kits are also described.
    Type: Grant
    Filed: August 19, 1991
    Date of Patent: October 26, 1999
