Expression of Hepatitis B Virus Surface Antigen Using a Baculovirus Vector with the Polyhedrin Gene
Abstract: Using a polyhedrin-positive transfer plasmid and a nonoccluded (OCC-) parental recombinant, an occluded (OCC~+)recombinant baculovirusdesignated TnNPV-HBs85-OCC~+ was successfully constructed which contained the gene coding for the hepatitis B virus surface antigen under the dual control of the synthetic and XIV promoters, Infection of Tvichoplusia ni larvae with TnNPVHBs85-OCC~+ can be introduced as a contaminant of the diet rather than the conventional baculovirus OCC~- expression vector in which the reco...
