Behavior of the Rheumatoid Arthritis Agglutinating Factor with Immune Precipitates,

Abstract

Summary The ability of rabbit immune precipitates to bind the agglutinating activating factor in the serum of patients with rheumatoid arthritis has been described and the interaction of the factor with a component of normal Fraction II is indicated. The significance of these findings with respect to the sensitized sheep cell agglutination and inhibition are discussed.
