ELECTRON MICROSCOPY

Sample

Human Ndc80 bonsai complex bound to the microtubule

Specimen Preperation
Sample Aggregation State FILAMENT
Vitrification Instrument FEI VITROBOT MARK I
Cryogen Name ETHANE
Sample Vitrification Details ?
3D Reconstruction
Reconstruction Method HELICAL
Number of Particles ?
Reported Resolution (Å) 8.6
Resolution Method FSC 0.143 CUT-OFF
Other Details Particles were initially aligned using IHRSR protocol in SPIDER with naked MT as reference. Final reconstruction and CTF correction was performed with FREALIGN. A B-factor of -450 was applied with BFACTOR. FSC was calculated only for MT and Ndc80-NUF2 head, disordered outer head was excluded with soft mask.
