casf might contribute to the permeability of the antigen into mucosa , enabling the carbohydrate epitope to interact with the allergy-specific ige distributed in conjunctiva and bronchi . in specificity analysis of a rabbit anti-diiia serum , a periodate oxidation- and acid-stable but heat- and alkali-unstable epitope ( type gamma ) in the protein moiety of diiia was also characterized as a useful marker of the antigen .
