Subcellular localization of TDE2508.
The whole cell lysate (WCL), soluble fraction (Sol) and envelope fraction (Env) of T. denticola ATCC 35405 were separated by SDS-PAGE with CBB-staining (A) and analyzed by Western blotting with anti-TDE2508 antiserum (B). The envelope fraction was further fractionated by differential solubilization in 0, 0.25, 0.5, 1, 2, 4, and 8% Triton X-100, and the soluble fractions (lanes 1–7, respectively) and insoluble fractions (lanes 8–14, respectively) were subjected to Western blot analysis with anti-T. denticola whole cell antiserum (C) and anti-TDE2508 antiserum (D). The grey, white and black arrowheads denote Msp, TmpC and TDE2508, respectively. M denotes a standard marker.
