Sample
ColicinE9 intact translocon complex

Specimen Preparation
Sample Aggregation State	PARTICLE
Vitrification Instrument	FEI VITROBOT MARK IV
Cryogen Name	ETHANE
Sample Vitrification Details	3 uL of diluted translocon preparation were applied on freshly glow discharged grids coated with graphene oxide (as described in https://doi.org/10.1038/s41594-019-0355-2); after 30sec waiting grids were blotted for 8-10 using -10 force and plunge frozen in liquid ethane
