Immune-Localization of MtrC, OmcA, and MtrB with Extracellular UO ₂ from S. oneidensis MR-1

<p>Whole-mount TEM images of MR-1 incubated with 100 μM U(VI) for 24 h and reacted with specific antibodies to MtrC (A, B), OmcA (C, D), or MtrB (E). High-resolution image of nanocrystalline UO₂ associated with the extracellular matrix and the 5-nm particles of colloidal gold (Au) (B, D). Extracellular matrix and cell labeled with colloidal gold in the absence of specific antibody (F).
