<strong>Purification / Growth Conditions / Treatment:</strong> 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. This time cell density was ~2.8</p>
<strong>Sample Preparation:</strong> 6 grids were frozen for this strain at OD~ 2.8, cell density was increased to 2x by centrifugation.

So, you can use the generic one for V. cholerae which is "666". The strain we are working with is related to N16961, but is certainly not the same strain, so not sure if you would want to indicate that somehow?

<strong>Collaborators and Roles:</strong> I received these cells from Carrie Schaffer from the university of Kentucky. These are wild type cells but they . don't express complete FliP protein. Therefore, they don't assemble full flagella. We knocked out FliM protein . of the flagellar motor to study the early assembly states of flagellar motor.</p>
<strong>Purification / Growth Conditions / Treatment:</strong> I grew the cells on blood agar plates from -80 stock at 37C with 5% CO2. the cells were grown . for 48 hours and then spread on a new plate with a cotton swab and left to grow for 24 hours. . The grids were prepared from both batches (48 hours, and 24 hours, separately).</p>
<strong>Sample Preparation:</strong> The samples were prepared with Vitrobot IV. Blotting conditions were either: blot force 6, blot . time 3, drain time 1 OR blot force -3, blot time 4, drain time 1, 100% humidity. Cu grids. 10 nm . gold.</p>
