Supercoiled plasmids (0 3 μg of each plasmid) were complexed with

Supercoiled plasmids (0.3 μg of each plasmid) were complexed with lipid (10 μl FuGENE HD reagent, Roche) in 200 μl serum-free medium. The complex was incubated at room temperature for 15 min, filled up with serum-free this website medium to 1 ml and then added to cells from which the growth medium was removed (cells were washed 1 × with serum-free medium). After 18 hrs, the complex suspension was removed and replaced by 3 ml of medium containing 10% (v/v) FCS. After further incubation for 24 h, the production of the proteins was induced by adding CuSO4 to a final concentration of 1 mM. Image acquisition Fluorescence microscopy was performed on an Olympus AX70 microscope with a Cool

Snap ES2 camera (Photometrics), TIRF microscopy was performed on an inverted Zeiss Axioobserver microscope with a TIRF incorporation from Visitron (Munich), and an Evolve EMCCD camera (Photometrics). Cells were mounted on thin agarose pads (1% w/v prepared in S750 minimal medium) on an object slide. DNA was stained with 4′, 6-diamidino-2-phenylindole (DAPI; final concentration 0.2 ng/ml), membranes with FM4-64 (Molecular Probes). Images were processed with Metamorph software. Acknowledgments buy SB273005 We thank Marcus Hinderhofer of the University of Konstanz for the gift of the yuaG (floT) in frame deletion strain, and Joel Defeu Soufo of the University of Freiburg for the gift of mreB strains.
