____43. These are called antibodies.  

____44.    These are capable of recognizing and binding to a specific antigen.

____45.    These are bound to the surfaces of mast cells and basophiles and are involved in

                  the allergic response

____46. These are responsible for cross-reactions between incompatible blood types.

____47. Produced by plasma cells.
