Summary Introduction
Introduction:
Immunoglobulin(Ig) are proteins mainly produced by plasma cells. IgE antibody is one of the classes of immunoglobulin (IgA, IgM, IgD, IgG, IgE). IgE plays an important role in type 1 hypersensitivity and various allergic diseases. Type 1 hypersensitivity is anIgE-mediated immune response. It is also called as immediate contact urticaria syndrome.
