           subtype:  opsonin  an antibody in blood serum that attaches to invading microorganisms and other antigens to make them more susceptible to the action of phagocytes
        subtype:  immunoglobulin_A__IgA  one of the most common of the five major classes of immunoglobulins; the chief antibody in the membranes of the gastrointestinal and respiratory tracts
        subtype:  immunoglobulin_D__IgD  one of the five major classes of immunoglobulins; present in blood serum in small amounts
        subtype:  immunoglobulin_E__IgE  one of the five major classes of immunoglobulins; present primarily in the skin and mucous membranes
           subtype:  reagin  an immunoglobulin E that is formed as an antibody against allergens (such as pollen); attaches to cell membranes causing the release of histamine and other substances responsible for the local inflammation characteristic of an allergy
        subtype:  immunoglobulin_G__IgG  one of the five major classes of immunoglobulins; the main antibody defense against bacteria
        subtype:  immunoglobulin_M__IgM  one of the five major classes of immunoglobulins; involved in fighting blood infections and in triggering production of immunoglobulin G
        subtype:  tetanus_immunoglobulin__tetanusimmunoglobulin__tetanusimmuneglobulin  sterile solution of globulins derived from the blood plasma of a person who has been immunized for tetanus; provides short-term immunization against tetanus in cases of possible exposure to the tetanus bacillis
  subtype:  coagulation_factor__coagulationfactor__clottingfactor  any of the factors in the blood whose actions are essential for blood coagulation
     subtype:  fibrinogen__factor_I  a protein present in blood plasma; converts to fibrin when blood clots
     subtype:  prothrombin__factorii  a protein in blood plasma that is the inactive precursor of thrombin
     subtype:  thromboplastin__thrombokinase__factor_III  an enzyme liberated from blood platelets that converts prothrombin into thrombin as blood starts to clot
     subtype:  calcium_ion__calciumion__factor_IV  ion of calcium; a factor in the clotting of blood
     subtype:  proaccelerin__prothrombin_accelerator__prothrombinaccelerator__accelerator_factor__acceleratorfactor__factor_V  a coagulation factor
     subtype:  proconvertin__cothromboplastin__stable_factor__factor_VII  a coagulation factor formed in the kidney under the influence of vitamin K
