NEW SERUM GROUP, GM(P).

The agglutination that occurs when rheumatoid arthritis serum Pond is added to erythrocytes sensitized with anti-D serum Moore is inhibited in the presence of some normal serums. The inhibitor, tentatively named Gm(p), is associated only with 7S gamma globulins and is apparently different from other previously defined serum groups. It is much more common in Caucasians than in Negroes, and probably is determined by a simple dominant gene.

Properties of guinea pig 7S antibodies. I. Electrophoretic separation of two types of guinea pig 7S antibodies.

Guinea pigs hyperimmunized with single protein antigens or hapten conjugates emulsified in complete adjuvants produced two types of precipitating antibodies with different electrophoretic mobilities. "Slow" migrating antibody generally appeared earlier and "fast" migrating antibody later in the course of immunization. Animals initially immunized by the intraperitoneal route with hapten conjugates without adjuvants produced primarily fast migrating antibody. Purified guinea pig antibodies were also separable into slow and fast migrating components by electrophoresis in supporting media. Using suitable antisera prepared in rabbits hyperimmunized with guinea pig serum, it was demonstrated that slow and fast antibodies have both common and distinct antigenic determinants. Analytical ultracentrifugation disclosed that both antibodies have sedimentation coefficients of approximately 7S. These antibodies have been designated guinea pig 7Sgamma(1) and 7Sgamma(2).

Complement fixation by antibody fragments.

Rabbit antibodies (7S) degraded by papain into univalent 3.5S fragments fail to fix complement when they combine, but do not precipitate, with the homologous antigens. Divalent 5S fragments obtained by pepsin digestion (composed of fragment I linked to II, but lacking fragment III) also fail to fix complement although they precipitate with homologous antigens. The amount of specific precipitate formed by the 5S antibody fragment is not increased by exposure to complement
