Abstract
Crossed immunoelectrophoresis (CIE) pattern of Yellow jacket vespid venom showing 25 immunoprecipitates was used in crossed radioimmunoelectrophoresis (CRIE) analysis with sera from 35 subjects allergic to vespid venom. Phospholipase A and B, hyaluronidase, acid and alkaline phosphatases and a lytic active component were demonstrated in immunoprecipitates using zymography and direct haemolysis of sheep erythrocytes. CRIE analysis proved the allergenicity of these proteins. In addition, another antigen (Ag17) with no detectable enzymatic or lytic activity was identified as an important allergen. This allergen is most likely identical to the previously described Antigen 5 in vespid venoms. By using CIE/CRIE the presence and complexity of multiple forms of the allergenic protein components were well demonstrated.
