According to the results obtained from Southern blotting, restriction mapping as well as partial DNA sequencing, the isolated genome (HPV6BV) had obvious variance and was referred to as a new variant of HPV6 found in China the first time. HPV6BV L1 gene was successfully expressed in E. coli as a fusion protein with pUR288. The β-galactosidase/L1 fusion protein reacted with both β-galactosidase antiserum and HPV antibody using Western blot technique. The E. coli-produced fusion protein, possessing HPV antigenicity, may provide a reagent for clinical diagnosis and epidemiological survey.展开更多
