SHV-12型超广谱β-内酰胺酶的原核表达及免疫原性分析
Prokaryotic Expression of SHV-12 Type ESBLs and Immunogenicity Analysis
摘要
Abstract
SHV-12 ESBLs target gene was amplified by PeR and subcloned into a vector pET-28a(+).The positive plasmid contained SHV-12 ESBLs gene was transferred into BL21(DE3) and was induced to expression and purification by IPTG.It proved that the SHV-12 ESBLs was expressed and purified as a molecular weight 30 KDa fusion protein which was verified by SDS-PAGE.Western blotting of the results showed that there was specific band.Nitrocefin colour reaction certificated that there was dynamic ESBLs.Inclusion body can stimulate Balb/c mice to produce high titer antibodies to 1∶106, which the recombinant ESBLs can be used as immune with good irnrnunogenicity.关键词
