title: Immunoblot analysis of IgE-binding antigens in spices.
abstract: The IgE response to coriander and other spices was studied by immunoblotting, after separation of the spice extracts by isoelectric focusing and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). A major IgE-binding component from coriander had an isoelectric point of pH5. After incubation of SDS-PAGE-separated spice extracts with serum from a patient with an occupational allergy to spices, a closely related pattern of IgE binding to coriander, dill and anise extract was observed. These results suggest that the botanically related spices, coriander, anise and dill, contain common IgE-binding structures.
