Fig. 3From: Serodiagnosis of human brucellosis by an indirect ELISA test using recombinant outer membrane protein 19 kDa (rOMP19) as an antigenPurified His-tagged OMP19 protein was chased via dot blot technique using commercial anti-His-tag peroxidase-conjugated antibody. A indicates negative control (total cell lysate of E. coli that not prompted by IPTG) and B: shows rOMP19 proteinBack to article page
