The baculovirus-insect cell expression system has been widely used method for the recombinant protein expression. The present study has several limitation. In this study, we constructed vectors consisting of transcriptional enhanced factor and promoter that improve the expression level. To confirm the usefulness of these vector system, Human papillomavirus (HPV) VLPs have been expressed by baculovirus hyper expression system. HPV VLPs were purified using a CaptoTM Core 700 (GE Healthcare Life Sciences) chromatography approach. Baculovirus hyper expression system production efficiency was influenced by the HPV VLPs production. HPV VLPs vaccination to BALB/c mice induced the generation of antibody confirmed by ELISA. This study could provide improvements on the vaccine production for the development of VLP vaccines high expression of useful heterologous proteins.
