The baculovirus expression vector system (BEVS) is an effective and widely used system for the production of recombinantproteins in insect cells or larvae. However, the expression efficiency of recombinant proteins using the polyhedrin promotercould not acquire the protein yields observed for native polyhedrin. In this study, we tried to develop hyper expressionvector by the optimal combination of previously reported various enhancer factors. The selected enhancer factors for optimalexpression consists homologous region5 (hr5), VP39 promoter and burst sequences. Seven recombinant viruses were madeto compare EGFP expression level. Each recombinant viruses showed different expression levels respectively, and themost of expression level was observed with higher than those of the previous vectors. This study suggests a new optionfor hyper expression of useful recombinant protein using the BEVS.
