#globulin  a family of proteins found in blood and milk and muscle and in plant seed
  supertype:  #simple_protein  a protein that yields only amino acids when hydrolyzed
  subtype:  #serum_globulin__serumglobulin  globulins occurring blood serum and containing most of the antibodies of the blood
     subtype:  #C-reactive_protein__CRP  a byproduct of inflammation; a globulin that is found in the blood in some cases of acute inflammation
  subtype:  #human_gamma_globulin__humangammaglobulin__gamma_globulin__gammaglobulin  a plasma protein containing the immunoglobulins that are responsible for immune responses
     subtype:  #immunoglobulin__Ig__immune_serum_globulin__immune_gamma_globulin__immune_globulin  a class of proteins produced in lymph tissue in vertebrates and that function as antibodies in the immune response
        subtype:  #antibody  any of a large variety of immunoglobulins normally present in the body or produced in response to an antigen which it neutralizes, thus producing an immune response
           subtype:  #autoantibody  an antibody acting against tissues of the organism that produces it
              subtype:  #rheumatoid_factor  autoantibody that is usually present in the serum of people with rheumatoid arthritis
           subtype:  #precipitin  an antibody that causes precipitation when it unites with its antigen
           subtype:  #ABO_antibodies  blood type antibodies
           subtype:  #Rh_antibody  rhesus factor antibody
           subtype:  #antitoxin  an antibody that can neutralize a specific toxin
              subtype:  #antivenin__antivenene  an antitoxin that counteracts the effects of venom from the bite of a snake or insect or other animal
              subtype:  #tetanus_antitoxin__tetanusantitoxin  antitoxin given for short-term immunization against tetanus in cases of possible exposure to the tetanus bacillus
           subtype:  #agglutinin  an antibody that causes agglutination of a specific antigen
              subtype:  #isoagglutinin  an antibody produced by one individual that causes agglutination of red blood cells in other individuals of the same species
           subtype:  #heterophil_antibody__heterophile_antibody__heterophileantibody__forssmanantibody  an antibody found in the blood of someone suffering from infectious mononucleosis
           subtype:  #isoantibody__alloantibody  an antibody that occurs naturally against foreign tissues from a person of the same species
           subtype:  #monoclonal_antibody  any of a class of antibodies produced in the laboratory by identical offspring of a hybridoma; very specific for a particular location in the body
           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:  #myosin  the commonest protein in muscle; a globulin that combines with actin to form actomyosin
