[Requirements for standards for monoclonal anti-A and anti-B antibodies].

On the model of the Soviet monoclonal anti-A and anti-B antibody--erythrocytes of the groups A1, A2, A1B and A2B the conditions for the elaboration of the branch standard for anti-A and anti-B monoclonal antibodies were worked out. In comparison with the standard for human sera determining the ABO groups, the requirement for avidity can be increased, furthermore it seems necessary to determine the percentage of non-A blood cells in the A2B group, which should not exceed 30%, and the percentage of non-B blood cells in A1B erythrocytes, which should not exceed 10%.
