The structural polypeptides of equine infections anemia virus.

The structural polypeptides and glycoproteins of equine infectious anemia virus were identified following electrophoresis in SDS-PAGE. The major non-glycosylated polypeptides had molecular weights of 25,000, 14,000 and 11,000 daltons. Two glycoproteins of 80,000 and 40,000 daltons were also detected. The relationship of these components to the structural elements of mammalian C-type oncoviruses is discussed.
