1. Claims for the Contracting States BE, CH, DE, FR, GB, IT, LI, NL, SE A process for determining the amount of prostatic acid phosphatase isoenzyme in a biological fluid sample, characterized by a) incubating the sample with (i) a soluble first antibody which selectively binds immunologically to the isoenzyme in the sample without inhibiting the enzymatic activity of this isoenzyme, and (ii) an insolubilized antibody formed by coupling this second antibody to amylose whereby the second antibody selectively binds immunologically to the first antibody without inhibiting the enzymatic activity of the isoenzyme, to obtain a precipitate of a mixture of immunocomplexes which contain isoenzyme-first antibody-second antibody and first antibody-second antibody, and b) isolating the precipitate containing the immunocomplexes and c) measuring the isoenzyme activity in the precipitate. 1.
