Below (a)is a diagramatic representation of the basic antibody structure.The loops and the chains themselves are held together by disulphide bonds.Below the structural diagram (b) is a computer generated 3-D model based on crystal structure.

The basic structure shown above is used to create different antibody types that are shown below.

The secondary response allows the immune system torapidly respond to antigents that have been previously seen by the immune system.
