Antibody - Wikipedia
An antibody (Ab), or immunoglobulin (Ig), is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.

Antibodies: Definition, Types & Function - Cleveland Clinic
An antibody is a protein produced by your immune system to attack and fight off these antigens. How do antibodies fight off antigens? The molecules on the surfaces of antigens differ from those found naturally in your body. So, when an antigen enters your body, your immune system recognizes it right away.

Antibody | Definition, Structure, Function, & Types | Britannica
Antibody, a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body. Learn more about the function and structure of antibodies in this article.

Types of Antibodies and Their Functions - Science Notes and ...
IgG is the most abundant antibody, accounting for 75%-80% of all antibodies in the body. It either tags an antigen for removal or it stimulates the production of toxins or other responses to destroy the pathogen.

Antibody: Definition, Structure, Types, Forms, Functions
Each antibody has two light chains that are identical and only one of the two (lambda (λ) and kappa (κ)) light chains is present per antibody in mammals; therefore either of the chains can occur in any of the 5 types of heavy chains.

Physiology, Antibody - StatPearls - NCBI Bookshelf
The five antibody classes produced by the body include IgG, IgM, IgA, IgD, and IgE. IgM is the first antibody produced and acts as a B-cell surface immunoglobulin (Ig).

Antibody - National Human Genome Research Institute
