title: Lp02_2nd

description: 2nd time collection: Jan 2016. Defocus -6.Lp02 is thymidine auxotroph of the parental strain Lp01 originating from Philadelphia-1 strain. 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

<strong>Purification / Growth Conditions / Treatment:</strong> Lp02 is thymidine auxotroph of the parental strain Lp01 originating from Philadelphia-1 strain. 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. Added gold before freezing.</p>
<strong>Sample Preparation:</strong> Grids were stored in Janelia from previous imaging. See previous Lp02 sample prep. 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.</p>
