p30-related proteins were examined in three in vitro -- passaged gross virus -- induced cell lines derived from mice congenic at the h-2 complex : balb.k-gv-1 ( h-2k ) ( bkgv1 ) , which produces infectious , oncogenic virus , and balb.b-gv-1 ( h-2b ) ( bbgv1 ) and balb/c-gv-1 ( h-2d ) ( bdgv1 ) , which stopped producing infectious virus early in their passage history .
