Mouse monoclonal anti-N. I. Production and serological characterization

Two examples of mouse monoclonal anti-N are described. The antibodies were derived from mice immunized with sialoglycoprotein extracts of group O MM ss erythrocyte membranes and the probable stimulus for immunization was glycophorin B associated N-antigen. Both antibodies reacted as direct agglutinins but appeared to recognize different epitopes with one having a greater dependence on sialic acid. The antibodies could prove to be valuable alternatives to those reagents used currently for N-blood grouping.
