Antibody

A type of protein made by white blood cells in response to an antigen (a foreign substance in the body). Each antibody binds to only one specific antigen and helps to destroy it. An antibody can work in several ways, depending on the nature of the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigens.
