Abstract
Summary
An electrophoresis-convection fractionation of a pool of syphilitic rabbit serum has been carried out. Significant differences in the mobilities of the γ-globulin components of these fractions have been demonstrated. No such differences in the mobilities of the β-globulin components were found. TPI, VDRL and agglutination studies were carried out. A comparison of the serologic and electrophoretic data indicates that the Wassermann reagin antibody is concentrated in the slow γ-globulin component and the T. pallidum immobilizing antibody is concentrated in the fast β-globulin component. There is no evidence for the concentration of T. pallidum agglutinating activity in any of the fractions.
