Fig. 4. Stochastic optical reconstruction microscopy (STORM) of E. coli imp4213 Δ6 BW25113 cells lacking all l,d-transpeptidases. Δ6 cells were labeled with Cy3BADA (A) and TDL (B). Left: Epifluorescence microscopy; right panel: STORM (right). E. coli imp4213 Δ6 cells were treated with cephalexin for 2 h, washed, and then pulsed with 1 mM Cy3BADA/TDL for 2 min. Insets in (A) and arrow head highlight a division septum. Scale bar: 2 μm.
