Figure 6. Subcellular localization of Rv0132c protein.
(A) Western blots of M. tuberculosis H37Rv subcellular fractions using 1/25000 dilution of anti–Rv0132c antiserum. Clear signals are found for the WCL, CW and CM fractions, but not for the SOL fraction. (B) Western blots of Triton X–114 treated fractions. The signal is present only in the DET fraction. WCL: whole cell lysate; CW: cell wall; CM: cytoplasmic membrane; SOL: soluble; AQU: aqueous fraction from Triton X–114 treatment; DET: detergent–enriched fraction from Triton X–114 treatment. In both panels recombinant Rv0132c–Δ38 protein (REC) is used as a positive control (0.7 µg).
