To explore the binding domains of rCIgE(301-376) necessary for inhibition of passive transfer of rye grass and Chinese elm IgE to human basophils, we employed monoclonal antibodies known to bind to IgE(301-336), M-272, and to IgE(367-376), M-27. By preincubating M-272, but not M-27, with rCIgE(301-376), passive transfer of specific IgE to basophils was partially inhibited. This implies that M-272 recognizes a binding site on rCIgE(301-376) or sterically interferes with the rCIgE(301-376) high-affinity binding domains on human basophils.
