Immunoglobulin (Microscopic 3D Schematic)
Antibody (Ab), also known as immunoglobulin (Ig), is a large Y-shaped protein mainly secreted by plasma cells and used by the immune system to identify and neutralize foreign substances such as bacteria, viruses, and other pathogens. It is only found in the extracellular fluid of vertebrates, such as plasma, and on the cell membrane surface of B cells. An antibody can uniquely recognize a specific foreign target through its variable region, which is called an antigen.
