Separation of antigens by immunological specificity: Use of disulphide-linked antibodies as immunosorbents.
1. gamma-Globulin concentrates of antisera prepared against ovalbumin and human serum albumin were thiolated and cross-linked to form insoluble polymers. 2. These immunosorbents were of low solubility and of high capacity for homologous antigen. 3. The high specificity of these immunosorbents was demonstrated by fractionation of various binary mixtures of fluorescent ovalbumin, (131)I-labelled human serum albumin, lysozyme and ribonuclease.
