Each antibody binds to a specific antigen; an interaction similar to a lock and key. An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to identify and neutralize pathogens such as bacteria and viruses.
Overview. Antibodies are a type of specialized protein generated by the immune system. Antibodies each contain two heavy chain proteins, which link to two smaller light chain proteins. The light chain contains a variable region that allows for an antibody to bind to one specific antigen.
