Data Taken By: Qing Yao

Species / Specimen: Caulobacter crescentus

Strain: NA1000

Tilt Series Settings: Single Axis, tilt range: (-60.0°, 60.0°), step: 1.0°, constant angular increment, dosage: 120.0 eV/Ų, defocus: -10.0 μm, magnification: 22500x.

Microscope: Caltech Polara

Acquisition Software: UCSFTomo

Upload Method: pipeline

Processing Software Used: Raptor

Purification / Growth Conditions / Treatment: C. crescentus was from Yi-Wei's cryo-stock and was grown in PYE medium overnight at 30°c 250 rpm. In the next days' morning, 1/20 subculture into the M2G medium. When OD600 reaches 0.48, 1ml medium was spun down and the resuspension was 100 ul for cryo-grid preparation.

Sample Preparation: Glow discharged Quantifoil R2/R holey carbon film. 4 ul concentrated gold suspension was added to 16 ul bacteria and mix before plunge freezing. Plunge freezing condition: 6(force)-2(duration time)-1(dry time). Tilt Series Setting: single tilt. constant angular increment, step: 1. tilt range: (-60, 60). dosage: 120/A2. defocus: -10um. magnification: 22500.
