ISOLATION AND PURIFICATION OF MAJOR OUTER MEMBRANE PROTEINS FROM BRUCELLA ABORTUS S-99
Isolation and purification of major outer membrane proteins (OMP) from the cell wall envelope of Brucella abortus S-99 were achieved by sonication, solubilization and membrane fractionation in the presence of non-ionic detergent (Tx-100) and lysozyme treatments, followed by ultracentrifugation. The crude OMP was treated with trypsin to free the preparation from any other protein contaminan...
متن کاملImmunization with a 22-kDa outer membrane protein elicits protective immunity to multidrug-resistant Acinetobacter baumannii
A. baumannii infections are becoming more and more serious health issues with rapid emerging of multidrug and extremely drug resistant strains, and therefore, there is an urgent need for the development of nonantibiotic-based intervention strategies. This study aimed at identifying whether an outer membrane protein with molecular weight of about 22 kDa (Omp22) holds the potentials to be an effi...
متن کاملProduction of antibody against a synthetic peptide of Porphyromonas gingivalis 40-kDa outer membrane protein.
Porphyromonas gingivalis has been implicated as a major pathogen in periodontal diseases. We previously cloned a 40-kDa outer membrane protein (OMP) gene from P. gingivalis 381 and succeeded in producing sufficient quantities of the recombinant protein for experimental use. Since antibodies against the recombinant (r) 40-kDa OMP have potent ability to kill P. gingivalis cells by complement acti...
متن کاملIsolation of the outer membrane and characterization of the major outer membrane protein from Spirochaeta aurantia.
The outer membrane of Spirochaeta aurantia was isolated after cells were extracted with sodium lauryl sarcosinate and was subsequently purified by differential centrifugation and KBr isopycnic gradient centrifugation. The purified outer membrane was obtained in the form of carotenoid-containing vesicles. Four protein species with apparent molecular weights of 26,000 (26K), 36.5K, 41K, and 48.5K...
متن کاملStudy of the immunogenicity of outer membrane protein A (ompA) gene from Acinetobacter baumannii as DNA vaccine candidate in vivo
Objective(s): Acinetobacter baumannii is one the most dangerous opportunistic pathogens in hospitalized infections. This bacterium is resistant to 90% of commercial antibiotics. Therefore, developing new strategies to cure A. baumannii-infections is urgent. The DNA vaccines new approach in which the immunogen can be directly expressed inside the target cells through cl...
