Collaborators and Roles: Strain sent to us by Joseph P. Vogel, Washington University School of Medicine. Data collected and processed by Debnath Ghosal at F30, Caltech.

Purification / Growth Conditions / Treatment: Cells were grown in AYE liquid culture with following supplements: ferric nitrate, cysteine hydrochloride and thymidine. Scrape cells off a plate, dissolve in the media, adjust the cell density to 0.6 and make a dilution series. Start O/N culture with all of them and freeze cells next day from the one in early stationary phase that is OD ~ 3.0.

Sample Preparation: 8 grids were frozen for the JV1644 strain at OD~2.9. Vitrobot (MK iv) settings: 100% humidity, 4µl sample, Blot force 6, blot time 3 sec. Wait time 0 sec. Drain time 1 sec. Ethane/propane mix. Grid: Quantifoil Cu 2/2 200. Add gold to cells prior to freezing: 1ul of gold to 4 ul of cells, freeze.
