antibody

A complex protein that is produced in response to the introduction of a specific antigen into an animal. Antibodies belong to a class of proteins called immunoglobins, which are formed by plasma cells in the blood as a defence mechanism against invasion by parasites, notably bacteria and viruses, either by killing them or rendering them harmless.
