An equation says that two things are equal. It will have an equals sign = like this: 7 + 2 = 10 â 1. That equation says: what is on the left (7 + 2) is equal to what is on the right (10 â 1) So an equation is like a statement this equals that. Here is another equation:
Detection of antibodies to gliadin, one of the major protein components of gluten, is a sensitive assay useful in diagnosing celiac disease. However, gliadin antibodies may be found in individuals without celiac disease; thus gliadin antibody assays are less specific than assays measuring antibodies to endomysium and transglutaminase.
Classes of antibodies: 1  IgG - provides long-term immunity or protection. 2  IgM - first antibody produced in response to an antigenic stimulus. 3  IgA - found in secretions.  IgE - involved in allergic 1  reactions. IgD - not much known about 2  it. Most important classes of antibodies in blood banking are IgM and IgG, and to a certain extent  IgA.
