Identification of RD5-Encoded Mycobacterium tuberculosis Proteins As B-Cell Antigens Used for Serodiagnosis of Tuberculosis

Figure 1

SDS-PAGE analysis of purified RD5-encoded recombinant proteins. Lane 1, molecular weight markers (SM0671, Fermentas, USA). Lane 2–6, purified Rv3117–Rv3121 recombinant proteins; molecular weight is 48.1 kDa, 11.2 kDa, 16.9 kDa, 38.2 kDa, and 45.3 kDa, respectively. Proteins were visualized with Coomassie brilliant blue staining.
