Species-specific and interspecific antigenic determinants associated with the structural protein of feline C-type virus
Abstract
The group-specific protein of feline leukemia viruses has been isolated by isoelectric focusing. This protein has a molecular weight, calculated from sodium dodecyl sulfate-acrylamide gel electrophoresis, of 25,000 and forms a resolved band in such gels when disrupted virions are analyzed. This protein contains both species-specific antigenic determinants, as well as interspecific cross-reactive determinants, as an integral part of its structure.
