Tobacco mosaic virus: a model antigen to study virus-antibody interactions.
For more than 50 years, tobacco mosaic virus (TMV) has been used as a model system for studying various aspects of virus-antibody interactions. Distinct epitopes called neotopes and cryptotopes have been identified in intact TMV particles and dissociated viral protein respectively and a correlation has been found to exist between the location of continuous epitopes and the extent of segmental mobility along the viral polypeptide chain. The occurrence of bivalent antibody binding was shown to influence the observed affinity of TMV antibodies and kinetic measurements of antibody binding to viral peptides made it possible to analyze the mechanism of binding of monoclonal antibodies. It seems likely that the TMV model will continue to yield a rich harvest of immunochemical data relevant to many viral systems.
