Abstract:
Specific series IgG4 titrate is realized now with a enzymo-immunologic using "double sandwich" method with allergen and patient serum in presence of a conjugate with peroxidase monoclonal Anti IgG4. Calibration obtains with a standard curve, is realized with a monoclonal IgG4 concentration is known. The first tests are in favor of correlation between specific IgG4 specific, IgE and in another way, the increase of specific IgE and specific IgG4 in a venom immunotherapy.
