Negative stain grids were prepared by applying the sample (3 uL) to the grid for 1 min, then blotting from the side to remove excess sample. The grid was washed immediately with 3 uL Buffer A, then blotted from the side. Concurrent with blotting, 3 uL of fresh 2% uranyl formate was applied to the grid, then blotted from the side. This step was repeated twice, then the grid was allowed to dry for at least 10 minutes.

450 tilt pairs were collected at -50 and 0 degrees.
 -50 0
Image tilt pairs were collected (-50 and 0 degrees) and particle tilt pairs were identified and extracted as two separate stacks. The untilted stack was aligned and classified iteratively, and RCT volumes were created for a single class average by applying alignment parameters to the corresponding tilt pairs.
