WebWe observed that GVs are highly sensitive to electron dose, losing high-resolution features quickly before deflating and shrinking . To mitigate this effect, we limited the total electron dose to ∼45 electrons/Å 2 per tilt series, which is ∼2.5 times lower than typically used for high-resolution subtomogram averaging.
