鹿结核分枝杆菌 MPB70蛋白的表达与免疫原性鉴定
Expression of MPB70 Protein and Identification the Immunogenicity of Deer Mycobacterium tuberculosis
摘要
Abstract
In this study,the immunogenicity protein MPB 70 gene was amplified from Mycobacte-rium tuberculosis genome DNA which separated from deer,and about 590 bp fragment was ob-tained.Then the fragment was cloned and constructed prokaryotic expression vector of pET-30a-MPB70,and the recombinant plasmid was put into E .coli BL21 (DE3).Purified after IPTG in-duction,and analyzed by SDS-PAGE,a specificity protein band was observed at 20 ku.Using the deer serum positive of tuberculosis in Western blotting,the fusion protein could be combined with deer serum positive of tuberculosis antibody and arise specific immune response.The protein could be used as a specific antigen to test the deer tuberculosis.The study laid a foundation for further studying the deer tuberculosis appraisal method.关键词
