【 摘 要 】

Brucella bacterium causes Brucellosis, an infectious disease spreading from animals to human. Brucella lumazine synthase (BLS) is a highly immunogenic protein with adjuvant properties, which has been introduced as an effective protein carrier for vaccine development. This protein also plays a significant role in inducing immune system. This study aimed to clone, express, and purify the BLS gene from Brucella melitensis Rev1. The BLS gene was amplified by particular primers with the restriction enzyme sites as a linker and it was inserted into pTZ57R/T vector. Subsequently, it was ligated into pET32(a)+ expression vector. Recombinant expression vector containing coding sequence of BLS was transformed into E. coli BL21 (DE3) host gene expression and stimulated by 0.1mM IPTG. The results of sequencing showed that there were not any mutations in BLS encoding sequence. The expression results were set by sequencing and endorsed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analyses and western blotting that showed 35 kDa protein band appropriately.
