abstract

  • It is well established that heat-denatured IgE is no longer capable of binding to FcepsilonRI. We have found an antibody that interacts with heat-denatured IgE. Interestingly, this antibody can also be used to detect some serum IgE, but not IgE synthesized de novo in vitro. However, native IgE can be transformed into an IgE that is recognized by this antibody, if antigen is added. Our data indicate that physiological mechanisms exist that biologically inactivate IgE which might still be mistaken for 'functional' IgE by assays based on polyclonal antibodies.
