Abstract

1. Process for binding, in an aqueous solution, an antigen which is specifically bound to a first antibody, and for separating this bound antigen from antigen which is not bound, for the determination of the antigen concentration in a body liquid with the aid of competitive radioimmunoassay, whereby the first antibody with the specifically bound antigen is separated from the free antigen which is dissolved in the aqueous solution, the separation being carried out by means of a second antibody, which is bound, on the one hand, to a Staphylococcus aureus cell, and, on the other hand, specifically binds the first antibody, and the process comprises adding a reaction accelerator to the aqueous solution, the reaction accelerator accelerating the specific binding of the first antibody by the second antibody, whereby 4-8 percent by weight polyethylene glycol, 5-10 percent by weight dextran, 5-10 percent by weight polyvinylpyrrolidone, 0,5-0,9 molar ammonium sulfate or 0,8-1,2 sodium sulfite are used as reaction accelerator.
