Fig. 4.
In vitro displacement of binding of [57Co]Cbl to viable and non-viable a E. coli and to b S. aureus; in vitro displacement of binding of [99mTc]PAMA(4)-Cbl to c S. aureus; viable bacteria at 37 °C (empty bar) or 4 °C (filled bar) and non-viable bacteria after ethanol fixation (diagonal hatched bars, E. coli only). Significant differences between binding in the absence and in the presence of cold Cbl (at different concentrations) are indicated as follows: *P < 0.05, **P < 0.005, ***P < 0.0005. Note that X- and Y-axes are scaled depending on the bacterium or radiopharmaceutical tested.
