Inhibition of passive sensitization of human peripheral basophils by synthetic human immunoglobulin E peptide fragments.

Abstract

To delineate the binding site in the human immunoglobulin E (IgE) molecule to the Fc epsilon receptor on basophils and mast cells, we chemically synthesized a total of 71 peptide fragments within the sequence Ser300-Lys547 in the human IgE molecule. The synthetic peptides were tested for their capacity to inhibit passive sensitization of human peripheral… (More)
