1	VAPOR DIFFUSION, HANGING DROP	6.65	293	Protein (9.6 mg/mL) was mixed with an equal volume (2 uL) of well solution comprising 200 mM sodium citrate (pH 6.65) and 24% (w/v) PEG3350. Cryoprotection was achieved by briefly (5-10 sec) swimming crystals in well solution doped with glycerol to a final concentration of ~25% (v/v), prior to snap freezing.
