Collaborators and Roles: 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 FliQ protein of the flagellar motor to study the early assembly states of flagellar motor.

Purification / Growth Conditions / Treatment: 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).

Sample Preparation: 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.
