title: Glycoprotein and protein composition of bovine leukemia virus (BLV).
abstract: Highly purified preparation of bovine leukemia virus (BLV) was obtained by the method described in this communication. BLV was isolated from cell-free culture medium, harvested from BLV-producing cell-line FLK. Polyacrylamide gel electrophoresis of BLV proteins and glycoproteins, in comparison with avian myeloblastosis virus (AMV), confirmed high purity of BLV preparations. Molecular weights of some BLV-proteins and glycoproteins were calculated. By employing polyacrylamide gradient 5 to 30% it was found that BLV structural protein p15 contains at least two components.
