An , also known as an immunoglobulin (Ig) , is a specialized Y-shaped protein produced by the immune system to identify and neutralize foreign substances like bacteria, viruses, and toxins. These invaders are known as antigens . 1. Structure of an Antibody
: The two arms that bind to antigens.
: Found at the tips of the "Y" arms, this region determines the antibody's specificity . It contains the paratope , which binds to a specific part of an antigen called an epitope .
: It consists of two identical heavy chains (~50 kDa each) and two identical light chains (~25 kDa each), held together by disulfide bonds.
