Some send chemical instructions (cytokines) to the rest of the immune system. Your body can then produce the most ...

... If an animal is immunized with a protein, a wide array of B cells will be stimulated to produce anti-protein antibodies. Antibodies may be made to a number of different epitopes of the protein. Even antibodies that bind to the same epitope may have different antigen-binding sites and bind the epitop ...
