1	VAPOR DIFFUSION, SITTING DROP		298	Purified RBD, Fab CR3022 and nanobody H11-D4 were mixed together at a molar ratio of 1:1:1 to a final concentration of approximately 7 mg/ml and incubated at room temperature for one hour. Initial screening was performed in 96-well plates using the nanolitre sitting-drop vapour diffusion method. The best crystals were grown in condition containing 0.1 M sodium citrate tribasic dihydrate, pH 5.0, 10% (w/v) Polyethylene glycol 6000.
