The Antigenic Composition of Rat Serum: an Electrophoretic Study

Abstract

Summary Pooled serums from normal, adult, male Sprague-Dawley rats have been analyzed by the electrophoretic methods of moving boundary, filter paper, polyvinylchloride block, starch gel, immunoelectrophoresis and starch gel immunoelectrophoresis. Immunoelectrophoresis has been found to be the most sensitive single procedure. Twenty-five antigenic components of rat serum were observed by this technique and a standard system of nomenclature was proposed. The antigenic heterogeneity of fractions separated by other methods was demonstrated.
