title: Monoclonal anti-human IgE: histamine release capacity and effect on in vitro sensitization of human basophils.
abstract: IgE-anti-IgE complexes were formed by preincubation of a human myeloma IgE with a monoclonal anti-human IgE antibody at different concentrations. Binding of IgE onto the anti-IgE inhibited the histamine release capacity of anti-IgE from basophils. The IgE cell-binding capacity was altered by the IgE/anti-IgE ratio in the preincubation buffer. Heating of the complexes gave a partial recovery of the anti-IgE degranulation capacity, suggesting that the monoclonal anti-IgE is specific for an epitope present on the D epsilon 2 domain.
