A variation of the radioimmune assay.
A novel method of radioimmune assay is described. It departs from conventional assays in that the radioiodine is reacted with protein following, rather than before, the antigen-antibody reaction. Using a BSA/anti-BSA system, the assay can detect antigen concentrations down to approximately 100 ng/ml.
