Allergen
Allergen (German: Allergen) is an antigen that specifically reacts with antibodies from people who have allergic diseases. Generally speaking what causes causes allergic symptoms, even those who are sensitized, but who do not have specific symptoms, the antigen that reacts with that antibody is also called an allergen. In a broader sense, it is a substance that can improve allergy causes, such as many allergic patients against it. Although it refers to a substance (antigen) itself that reacts with an antibody to cause allergy, it often refers to a substance (food, etc.) containing the antigen. For example, proteins contained in pollen such as Cry j 1 (Cry jayan) have been identified as allergens in Japanese cedar pollinosis, but in general allergens from cedar pollinosis are recognized as cedar pollen. ...
