Technical info

Tilt Series Date: 2014-02-14

Data Taken By: Yi-Wei Chang

Species / Specimen: Helicobacter pylori

Strain: 26695

Tilt Series Settings: Single Axis, tilt range: (-60.0°, 60.0°), step: 1.0°, constant angular increment, dosage: 210.0 eV/Ų, defocus: -10.0 μm, magnification: 22500x.

Microscope: Caltech Polara

Acquisition Software: UCSFTomo

Upload Method: pipeline

Processing Software Used: Raptor

Collaborators and Roles: H.pylori & AGS cells from Carrie Shaffer

Purification / Growth Conditions / Treatment: H.pylori cells grown in BLBB + 5% heat inactivated fetal bovine serum at 37 degrees in 5% CO2 chamber for O/N, OD600=~0.5. AGS cells cultivated on QF Au finder grid for 1 day in RPMI + 10% FBS. Infect by pylori for 4 hr.

Sample Preparation: Vitrobot settings: 100% humidity, 37 C, 3µl BSA treated 20 nm gold (100 ul gold+ 25 ul BSA, pellets from 6 tubes merged into ~30 ul final solution). Manual blot by Whatman 40 filter paper for 3 sec. Ethane/propane mix.
