結(jié)核分枝桿菌rBCG-Rv2029c重組疫苗的構(gòu)建與鑒定
[Abstract]:Objective to construct and identify rBCG-Rv2029c recombinant vaccine of Mycobacterium tuberculosis. Methods the Rv2029c antigen coding gene was amplified by PCR, then the Rv2029c and pMV261 plasmids were digested by double enzyme digestion, and then the digested products were ligated into rpMV261-2029c recombinant plasmid, and the plasmid was introduced into BCG to construct rBCG-Rv2029c recombinant vaccine by electroporation. Finally, the expressed recombinant protein was identified by SDS-PAGE and Western blotting. Results the 1 020bp Rv2029c gene was successfully amplified by PCR and inserted into pMV261 plasmid, and then the fusion gene was successfully introduced into BCG. It was confirmed by double enzyme digestion and gene comparison that the recombinant protein had immunogenicity by Western blotting after heat induction. Conclusion the recombinant live vaccine of Mycobacterium tuberculosis rBCG-Rv2029c was successfully constructed, which laid a foundation for the study of the immune mechanism of the recombinant vaccine.
