Recombinant dengue virus type 2 envelope/hepatitis B surface antigen hybrid protein expressed in Pichia pastoris can function as a bivalent immunogen.

A truncated version of the dengue virus type 2 envelope protein (Den2E) encoding the first 395 amino acid (aa) residues, and Den2E fused in-frame with the full-length 226-aa hepatitis B surface antigen (Den2E-HBsAg) protein were expressed in the methylotrophic yeast, Pichia pastoris. Both the recombinant proteins showed evidence of the capacity to form high… (More)
