Novel glycolipid variations revealed by monoclonal antibody immunochemical analysis of weak ABO subgroups of A
Background and Objectives The chemical basis of the subgroups of A is largely unknown. We used thin-layer chromatography immunochemical staining techniques together with a range of characterized monoclonal reagents to analyse glycolipids isolated from a variety of weak subgroups. Materials and Methods Glycolipids isolated from red cells collected from nine genetically defined individuals of the ra
