 ETHANE 100 FEI VITROBOT MARK II Sample was incubated on grid for 30 seconds before blotting 6.5s at -1 offset. The grid was washed in 4 ul buffer to blot again for 6.5 s at -1 offset prior to plunging.

Particles were prepared within the APPION processing environment. The particles were automatically selected using Signature and extracted from phase flipped micrographs using values calculated by CTFFIND3. After projection matching within EMAN2/Sparx, the final map was further refined in FREALIGN.
Per micrograph for phase flipping, per particles for refinement in FREALIGN
