Abstract:
High performance liquid chromatography (HPLC) with a TSK-4000SW gel filtration column was used to compare envelope polypeptides from four strains of herpes simplex virus type 1 (HSV-1). The chromatographic profiles demonstrated polypeptide variability among three clinical strains and the wild-type F strain. Radioimmunoprecipitation of the HPLC fractions with polyclonal anti-HSV-1 followed by SDS-polyacrylamide gel electrophoresis (PAGE) of the immunoprecipitates revealed molecular weight differences of various polypeptides in fractions from the area containing major peaks. This HPLC method could prove useful for the analysis of polypeptide polymorphism in clinical isolates of HSV-1, as well as in other viruses.
