An antibody is a protein produced by the body's immune system when foreign objects are detected.The antibody recognises a specific site on the foreign target called antigens.

The antibody then binds to the antigens in order to remove them from the body. A wide range of substances are regarded as antigens, such as toxic materials like insect venom [1].

However, antibodies can also be produced when healthy tissue is mistaken for a harmful substance by the immune system. This is known as an autoimmune disorder [2].
