Abstract
Objective:To investigate the correct expression of dengue 2 virus 43 strain NS1 gene in transfected BHK-21 cell. Methods:The D2-43 DNA fragment coding for signal peptide plus NS1 protein was cloned between KpnⅠ site and EcoR Ⅰ site of expression plamid pcDNA3.1. The obtained recombinant vector pcDNA-NS1 was transfected into BHK-21 cells with electroporation technique. After selection by G418, resistant clones were screened by RT-PCR and Western blotting test. Results:The RT-PCR results of four in five randomly selected cell clones were positive. Western blotting test showed that NS1 gene could be expressed in BHK-21 cells. Conclusions:NS1 protein was capable of being expressed and appropriately processed in pcDNA-NS1 transfected BHK-21 cells. The present results suggest the feasibility of NS1-based DNA immunization.关键词
