Fig. 1From: Recombinant E2 protein enhances protective efficacy of inactivated bovine viral diarrhea virus 2 vaccine in a goat modelCloning and expression of the BVDV E2 gene. The E2 gene of BVDV/TW2008 was cloned for expression in a baculovirus expression system and the sequence was compared to that of other BVDV-2 strains (a). Expression and quantitation recombinant E2 (rE2) was done using SDS-PAGE analysis (b). Antigenicity was verified using bovine convalescent anti-serum (c)Back to article page
