ELECTRON MICROSCOPY

Sample

Rat TRPV1 in complex with capsaicin

Specimen Preperation
Sample Aggregation State PARTICLE
Vitrification Instrument FEI VITROBOT MARK III
Cryogen Name ETHANE
Sample Vitrification Details Blot for 6 seconds before plunging into liquid ethane (FEI VITROBOT MARK III)
3D Reconstruction
Reconstruction Method SINGLE PARTICLE
Number of Particles 33238
Reported Resolution (Å) 4.2
Resolution Method FSC 0.143 CUT-OFF
Other Details The entire ankyrin structure was fitted as a single rigid body. As a result, the first two ankyrin repeats (UNP residues 111-199) are included but are not well defined by the experimental density. (Single particle details: 3D classification, refinement, and reconstruction were performed using RELION) (Single particle--Applied symmetry: C4)
