Monoclonal antibody
Antibodies that have been produced in a lab to 'recognise' and stick to a particular molecule. mAbs can be engineered to stick to virtually anything - including viruses, bacteria and specific proteins on the surface of a cell. Because of this property, mAbs have proved extremely useful for lab studies and are now being developed and used as drugs. The breast cancer drug Herceptin is a mAb that binds to a protein called HER2 on the surface of breast cancer cells.
