Antihaemophilic globulin

Anti-idiotype antibodies
Antibodies which recognize the binding site of other antibodies. Their binding sites are complement to the binding sites of another immunoglobulin. When animal becomes immune to something, it not only acquires antibodies against that something, it also acquires antibodies against those antibodies. This forms a network of antibodies which can all bind to each other to various degrees, helping t regulate the immune response. Some allergic responses are' part due to the breakdown of this sort of regulation.
