Abstract

Molecular biology has made tremendous strides over the last five years. The new biology allows us to prepare monoclonal antibodies to defined antigens; to detect, isolate and clone specific genes; and to insert these genes into defined sites in different cells giving new functions to old organisms. These revolutionary developments have been followed closely by researchers, businessmen, politicians and philosophers, as well as by those involved in the clinical care of patients. Although our understanding of human molecular biology is increasing rapidly, it is the development of monoclonal antibodies that has the most immediate application in the clinic. There have been several reports of their use in the diagnosis, localisation and treatment of human malignant disease. This review describes developments that are likely to have direct relevance to patient care in the near future.
