To evaluate in vitro the mechanism of function of Brucella major outer membrane proteins and the interaction with cells. The Brucella outer membrane proteins Omp10, Omp16, Omp19, Omp25, Omp28, Omp31, Omp2a genes were cloned to pMD18-T simple carrier; Liked them to the carrier pefgp – n1 for eukaryotic expression; Examined the carrier on HEK 293 cell and detected the transfection efficiency. Cloned Brucella main outer membrane proteins and constructed their eukaryotic expression vectors, further examined the transfection efficiency on HEK 293 cells. Built carriers have happened expression in HEK 293 cells. This study provided the necessary materials for later research on relationships between cells and Brucella main outer membrane proteins.
