Vitrified specimens were prepared by adding 2.5 uL of liganded protein at 1.8 mg/ml to R2/2 holey carbon grids (Quantifoil, Jena, Germany) rendered hydrophilic by chemical treatment to enable particle distribution into the holes (Meyerson JR, Rao P, Kumar K, Chittori S, Banerjee S, Pierson J, Mayer ML, and Subramaniam S, manuscript in preparation).
