The Structure and Evolution of the HLA-Bw4 and Bw6 Antigens

Abstract
The HLA-Bw4 and Bw6 antigenic determinants co-migrated with HLA-B determinants on gel-filtration, sucrose density gradient centrifugation and affinity chromatography, using Lens culinaris lectin and antibody against human .beta.2 microbulin. The HLA-Bw4 and Bw6 determinants apparently reside on the same polypeptide chain as other HLA-B locus determinants. The implications of this in terms of the evolution of cross reacting groups of antigens at the HLA-B locus were discussed.
