title: Studies on the human basophil IgE receptor. Generation and characterization of monoclonal antibodies against the receptor.
abstract: Anti-human basophil IgE receptor (Fc epsilon R) monoclonal antibodies (McAbs) were generated and characterized. The production of these antibodies was facilitated by both a single step procedure for the enrichment of basophils using Ficoll-Paque centrifugation and a double staining technique combining the APAAP with alcian blue. By the double staining technique we could recognize the specific anti-basophil antibodies because the cells binding the antibody--APAAP positive cells--also had alcian blue-stained basophil granules. Blocking experiments showed that the McAb was directed against the Fc epsilon R since preincubation with human IgE blocked the binding of the McAb and preincubation with the antibody blocked the binding of IgE to basophils and inhibited the formation of IgE rosettes.
