Two populations of Ia-like molecules on a human B cell line.
摘要:
Evidence is presented for two populations of Ia-like molecules on the human B cell line Raji. Two monoclonal antibodies, L203 and L227, are described. Both recognize nonpolymorphic determinants on B cell antigens. Both immunoprecipitate 34,000- and 28,000-dalton material from 125I-labeled extracts of Raji, but L227 precipitates 25,000-dalton material as well. Immunodepletion experiments confirm that the antibodies react with two different populations of molecules.
