Overview
Antibody Isotypes are proteins produced by the immune system that identify and neutralize foreign substances in a body. They are an important part of the body’s natural defense system, as they can recognize specific antigens, bind to them, and elicit an immune response. Different isotypes of antibodies function differently, and each has a unique structure specialized to recognize and bind to a particular antigen. There are five main classes of antibody isotypes; IgA, IgD, IgE, IgG, and IgM, and they play important roles in many physiological processes, such as inflammation, neutralizing toxins, and providing protection against microorganisms and infectious diseases. Additionally, they are increasingly being used to diagnose and treat certain illnesses, as they can be used to manufacture immunotherapies and targeted treatments.
