A protein belonging to the class of proteins called immunoglobulins. Antibodies are produced by plasma cells to counteract specific antigens or foreign proteins (including infectious agents like viruses, bacteria, etc… or venom). The antibodies then combine with the antigen they are made to fight and often cause the death of that infectious agent. Their presence helps prevent symptoms or disease processes on further exposures to the same antigen.
