PROCESS FOR BINDING AND SEPARATING IN COMPETITIVE RADIOIMMUNOASSAY, AND REAGENT FOR THIS PURPOSE

摘要

: HOE 80/F 156 Process for binding and separating in competitive radioimmunoassay, and reagent for this purpose A process is described for binding an antigen, which is specifically bound to an antibody, in an aqueous solution, and for separating off this bound antigen for the determination of the antigen concentration in a body fluid, wherein the antibody with the specifically bound antigen is separated off from the free antigen which is dissolved in the aqueous solution, a reaction accelerator being added to the aqueous solution. Polyethylene glycol, dextran, polyvinylpyrrolidone, ammonium sulfate or sodium sulfite serve as reaction accelerators.
