[Study on immunogenicity of DNA vaccine encoding human cytomegalovirus gB and pp150 fusion gene].

Objective: To provide experimental evidence for development of human cytomegalovirus (HCMV) nucleic acid vaccine, HCMV surface protein (gB), membrane protein (pp150), and gB-pp150 fused gene eukaryotic expression vector were constructed.

Methods: gB and pp150 genes were amplified and fused into gB-pp150, then were cloned into pcDNA 3.1 (+) to obtain recombinant expression plasmids pcDNA 3.
