Differentiation of Newcastle disease virus strains by one-dimensional peptide mapping.
One-dimensional peptide mapping was used for the differentiation of Newcastle disease virus (NDV) strains. Virions were purified in one step, and digested with Staphylococcus aureus V8 protease or chymotrypsin without prior separation of their proteins. Peptides were separated by polyacrylamide gel electrophoresis and stained with Coomassie blue. This method proved to be a simple, economic and reproducible means of differentiating NDV strains.
