Specific antibodies for desialized M and N blood group antigens

Vox Sanguinis
E Lisowska, M Kordowicz


Antisera obtained by immunizing rabbits with desialized M and N blood group glycoproteins (M' and N' glycoproteins) agglutinate desialized erythrocytes and precipitate desialized glycoproteins, but they do not react with sialic acid containing erythrocytes or glycoproteins. By absorption of anti-M' serum with N' glycoprotein, and of anti-N' serum with M' glycoprotein, reagents specifically agglutinating M' or N' erythrocytes were obtained. The absorbed anti-M' and anti-N' sera were specifically inhibited by M' or N' glycoproteins, respectively. The results show that sialic acid residues of red cell glycoproteins are not essential for the differentiation of M an N blood group determinants.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
