Monoclonal antibody technology: applications in veterinary science.
Monoclonal antibodies have revolutionised the study of animals and their diseases. The author looks at the detection of antigen in samples using a range of techniques from indirect fluorescence, through in-situ hybridization to enzyme linked immunosorbent assays. Examples are given of how Salmonella species, mastitis antigens, viral antigens, chlamydial organisms and E. coli toxins can be detected using specific monoclonal antibodies. The recognition of antigen in tissues by monoclonal antibodies is also discussed using as examples; the vitamin biotin, the chicken anemia virus, the growth promoter clenbuterol and the bovine lymphokine, gamma interferon. The ability of monoclonal antibodies to measure specific antibody is also discussed, with particular reference to chicken anemia agent. The review concludes with a discussion of the ability of monoclonal antibody based ELISAs to discriminate between pigs naturally infected with Aujeszky's disease and those vaccinated against the condition.
