狂犬病病毒HEP-Flury株N基因的修饰及原核表达
Modification and Prokaryotic Expression of Nucleoprotein Gene of Rabies Virus Strain HEP-Flury
摘要
Abstract
Using bioinformatics analysis, a rich antigenic determinant area in HEP-Flury nucleoprotein sequence was selected, and the codons were modified to cater the codon usage bias in Escherichia coli, and the restriction enzyme sequences were inserted in upstream and downstream. The modified gene was synthesized and cloned into prokaryotic expression vector pET-32a( + ). The recombinant plasimd was designated pET-32-NP. pET-32-NP wasl75 transformed to E. Coli BL21 ( DE3)pLysS, and the recombinant protein was expressed after IPTG induction. SDS-PAGE analysis showed that the expressed protein had a relative molecular mass of 34 000. Western-blotting results also revealed that the expressed protein could be recognized specifically by mouse anti-His monoclonal antibody and mouse anti-RV polyclonal antibody.关键词
