[Radioimmunoelectrophoretic determination of alpha-fetoprotein. Standard inhibition curves].

The author suggests an express method of radioimmunological determination of murine and human alpha-fetoprotein with the use of electrophoretic separation of immune-bound and free antigen. The method is comparatively simple, it permits to analyze up to 50 samples in the course of 5 hours. Behaviour of the antibody-antigen system in drawing the standard inhibition curves was analyzed. Inhibition of the antibody-antigen reaction in the zone of low and great concentrations was revealed. The effect described requires further study.
