Fig. 3. Confocal images comparing the Pal deletion strain with WT E. coli. Pseudo-colour confocal images show that the E. coli Pal deletion strain does not fluoresce when incubated with anti-Pal and Alexa Fluor 488 (b) or Alexa Fluor 647 (d). (a) and (c) show the E. coli parent strain fluorescing under the same incubation conditions, respectively. Bars, 10 μm.
