Allergens are foreign normally environmental antigens that induce a specific immune response and trigger an allergic reaction. Most antigens are protein or glycopeptides of certain physical characteristics. The tendency for a substance to be more allergic is its ability to penetrate skin or mucosal surface, low molecular weight and good solubility and stability. Inhalational allergens include pollen, molds, animal dander. Ingestional allergens are food and medication that enter body via digestive system.
