Human papillomavirus type 16 E6 gene's T-A cloning and expression in insect cell
Abstract: The baculovirus insect cell expression system was used to prepare the HPV16 E 6 recombinant protein. The HPV16 E 6 complete ORF amplified by PCR from HPV16 genome was T A cloned into the baculovirus transfer vector pVL1393 T under AcMNPV Polh. This recombinant transfer plasmid pVL1393 E 6 DNA and baculovirus DNA were co transfected into insect cell Sf 9. After the plaque screening, the recombinant baculovirus AcMNPV E 6 was expressed in insect cells. The E 6, analysised by SDS PAGE, was 18kD, and was recognized by antibody against E 6 protein, which showed their natural antigenecity.
