title: Affinity electrophoresis used for determination of binding constants for antibody-antigen reactions.
abstract: The use of affinity electrophoresis in agarose gels for determination of binding constants for the interaction of antigens with monoclonal antibodies is exemplified for monoclonal anti-human serum albumin and anti-alpha 1-fetoprotein antibodies. The calculated binding constants are verified by independent binding assays. The electrophoretic separation of antigen-antibody complexes of different stoichiometry is also demonstrated. Thus, affinity electrophoresis represents an alternative method for both qualitative and quantitative assessment of antigen-antibody interactions.
