1. The microheterogeneous alpha molecules of class II antigen, DR molecules obtained from human B cell line and I-A molecules from mouse B cell hybridoma cell line, were separated by 2-D PAGE, transferred onto NC sheets and N-linked oligosaccharide types were analyzed by staining with P.O./lectins. 2. This is the first report to show directly the type of oligosaccharide chain corresponding to each spot separated by 2-D PAGE. The glycosylation patterns of class II alpha chains in human and mouse were compared.
