Fig 2. TP4 peptides existed in small dots in E. coli under fluorescent confocal microscope.

The non-fixed (B) and GA-fixed (D) E. coli (1x10⁷ cfu) were incubated with 5 μg FITC-TP4 peptides in 200 μl phosphate buffer and examined under confocal fluorescence microscopy CLSM 700. No peptide was added in non-fixed (A) and glutaraldehyde-fixed (C) E. coli cells. Small dots are shown in the insets of panel B and D at high magnifications.
