An antibody is a protein that is produced by the immune system in response to the presence of a foreign substance, such as a bacterium or virus. Antibodies are made up of two heavy chains and two light chains. The heavy chains are about 450 amino acids long, and the light chains are about 220 amino acids long. The heavy and light chains are linked together by disulfide bonds.
