Antigenic characterization of c-type oncornavirus isolated from lymphomatous baboon (Papio hamadryas)

Antigens of BILN C-type oncornavirus isolated from lymphomatous baboon were studied in the double immunodiffusion. The major viral protein (P-30) of this virus possesses interspecies antigenic determinants (GS-3). This protein also revealed close antigenic relation to the P-30 of RD-114 and M-7 C-type oncornaviruses. Specific serum against BILN P-30 has been produced. The comparison of the three test-system (P-30s of M-7, RD-114, and BILN, and specific sera against them) did not allow to distinguish these proteins by the method used.
