Figure 1From: A baculovirus dual expression system-based vaccine confers complete protection against lethal challenge with H9N2 avian influenza virus in miceSchematic representation of BV-Dual-HA structure. The gene cassette consists of the gp64 signal peptide (SP), the HA ectodomain gene, the HA transmembrane domain (TM), gp64 cytoplasmic domain (CTD), and poly(A). The dual promoter that consisted of the CMV immediate early enhancer/promoter (pCMV) and the polyhedrin promoter (pPH) drove expression of the gene cassette.Back to article page
