Sera and effusion fluids of patients with breast cancer (BC) contain immune complexes (IC). Antigens present in these complexes were isolated as follows: a pool of effusions from patients with BC was fractionated with ammonium sulfate. The proteins precipitating at 40% saturation were further fractionated by filtration through a Sephadex G-200 column. The material recovered in the first peak (molecules larger than monomeric IgG) was brought to pH 3.0 to dissociate the IC, and the mixture was filtered through a column of Sephacryl S-300 at pH 3.0. Proteins smaller than monomeric IgG were collected, radioiodinated, and used as antigens (125Ag) to search for corresponding antibodies in sera of patients with BC (BCS) and of healthy individuals (NHS). 125Ag was reacted with the sera and the immune complexes obtained were precipitated with an antiserum to human Ig and analyzed by SDS-polyacrylamide gel electrophoresis followed by autoradiography. Both NHS and BCS contained antibodies against two antigens; one of these appeared as a strong band of 17KD, the other as a doublet of approximately 25KD. It is concluded that some of the proteins in the IC from patients with BC are auto-antigens. No BC-specific antigens were identified.
