Structural proteins of ribonucleic acid tumor viruses. Purification of envelope, core, and internal components.
Murine type C virus structural proteins, the envelope glycopeptides, 30,000 dalton major core protein, and 15,000 dalton internal protein have each been purified to near homogeneity and in high yield from the smae batch of virus by use of phosphocellulose column chromatography and gel filtration procedures. Evidence that these proteins are specified by the viral genome was obtained by competition radioimmunoassay analysis, comparing these polypeptides from Rauscher virus cultivated in a variety of mammalian cell lines; all of the reactive antigenic determinants of these proteins appeared to be virus-specific.
