What if the function of the antibody?

Answer 1

An antibody is a Y shaped proteins that are cruical to the specific immune response and are released by lymphocytes. The top "arms" of the Y have sites that recognise and bind specfic counterparts, other proteins called antigens, on cells that are not SELF (cells that are part of the organism producing the antibodies). Each of the arms on one antibody recognises the same antigen as it partner arm and so each antibody binds two atingens. This mean that potentially two cells can be bound together and this is the primary function of antibodies, to bind masses of cells together making them inefctive at damaging SELF cells and as a mass they are phagocytosed by macrophages. Antibodies are also present on T-lymphocytes which use them to recognise non-self cell and directly destroy them.
