    Molecular Biology by Robert F. Weaver



Antigen Notes:

Antigen (Ag) is a structure or a substance that is recognized and specifically bound by an antibody (Ab). It is basically a foreign substance or a toxin, that induces an immune response in the body, leading to the production of antibodies. The term antigen describes a structural molecule that binds to a specific antibody, only in the form of native antigen.
