[Heterogeneity of monoclonal antibody affinity]

In experiments with Pasteurella pestis monovalent capsular antigen and hybridoma monoclonal antibodies obtained after cloning and recloning the heterogeneity of the active centers of antibodies with respect to their affinity was revealed. In ascitic fluids obtained from the animals inoculated with different hybridoma clones 5 groups of antibodies, differing in their affinity, were determined in each fluid sample.
