        Membrane-bound antibodies
        
        Found on surface of B-lymphocytes
        
        Secretory antibodies
        
        B cells stimulated to produce this type of antibodies
      - Structure
        
        4 polypeptide chains
        
        2 light chains
        
        2 heavy chains
        
        disulfide bridge
        
        Hypervaribale region

        Variable region
        
        Fab segment
        
        1 constant and 1 variable domain of each of the heavy and light chain
        
        Constant region
        
        determines what class the antibody belongs to
        
        Ig G, Ig A, Ig M, Ig E, Ig D
        
        activate the immune system
