Abstract

Direct evidence is provided for the antigen binding activity of the 6S subunits formed by reduction and alkylation of rabbit β2-macroglobulin antibody. Binding activity of the subunits was clearly demonstrated by radioimmunoelectrophoresis with a preparation of purified rabbit antibody against the p-azobenzenearsonate group, which contained 40 percent of β2M-antibody. The precipitate arc formed between the subunits and sheep antiserum against rabbit macroglobulin was shown to bind radioactive antigen specifically.
