To prepare negative stain grids, a 4 uL aliquot of each complex, which had been diluted to a concentration of ~0.03 ug/mL with TBS buffer, was placed for 15 seconds onto carbon-coated 400 Cu mesh grids that had been plasma cleaned for 20 s (Gatan), blotted off on the edge of the grid, then immediately stained for 30 s with 4 uL of 2% uranyl formate. The stain was blotted off on the edge of the grid and the grid was allowed to dry.
