Methods The HPV16E7 gene was cut to three parts, amplified by PCR, and connected individually with BPVL1 on plasmid PUC. With PVL1393 as a transfect vector, the BPVL1/HPV16E7 recombinants were transfected to baculovirus which subsequently expressed the chimeric BPVL1/HPV16E7 protein in the SF－9 cells. The recombinant proteins were then purified by centrifuge, sonication, sucrose and CsCl ultracentrifuge, and were identified by SDS-PAGE, Western blot, ECL and TEM.
