Abstract
The cattle V antigen from the FV blood group system was characterized. Hemolytic as well as immunochemical analyses with monoclonal antibody (MAb) IVA-41 found that V antigen of bovine red blood cells is a membrane-bound, papain- and pronase-sensitive, trypsin- and chymotrypsin-resistant N-glycosylated sialoglyco-protein with molecular weight of 64, 56, and 50 kDa under no reduction and 23 kDa under reduction conditions. In contrary to some human blood group antigens, the expression of bovine blood group V antigen is restricted to the erythrocyte membrane.
