A nonimmunoglobulin precipitin to tissue extracts in pathological human sera
1Department of Microbiology, School of Medicine, State University of New York, Buffalo 14214.
Abstract:
An alpha-globulin component was noted in pathological human sera, which produced gel precipitation reactions with extracts of human and animal liver. The highest incidence of the precipitin was found in malaria (95%), renal graft rejection (81%), and rheumatoid arthritis (57%). The precipitinogen was thermostable and ethanol soluble; of two precipitation lines formed by this component, one merged into identity reaction with a line produced by commercial lecithin of bovine origin. The possible diagnostic application of the reactions noted was considered.
