[Prokaryotic expression of HPV 16 L1 gene and identification of its immune activity].
OBJECTIVE
To express the major capsid protein of human papillomavirus type 16 L1(HPV 16 L1) in E.coli and identify its immune activity.


METHODS
The L1 gene of HPV 16 was cloned into the expression vector pThioHisC. The recombinant expression vector was transformed into E.coli, and the HisC-L1 protein was expressed under IPTG induction. The fusion protein was characterized by SDS-PAGE and Western blot.


RESULTS
The HPV16-L1 gene in plasmid pThioHisC was expressed in E.coli as a fusion protein with M(r) about 70,800. The fusion protein reacted specifically with antibodies against HPV16-L1.


CONCLUSIONS
The HPV-16 L1 gene was expressed successfully in E.coli, which provides necessary basis for preparing HPV-16 L1 vaccine in human.
