Confocal microscope images of <i>E. coli</i> in the presence of CF-labeled HC-1(R), [D]HC-1(R) and [D]HC-3(R).

<p>Bacterial cells (1 x 10⁷) were treated with CF labeled peptide and FM4-64 and were incubated for different time points. Panel A represents an early time point where the peptide interacts with the bacterial membrane. Panel B represents a late time point wherein the peptide is found completely diffused inside the cell. The bar represents 5 µm.
