1	VAPOR DIFFUSION, SITTING DROP		295	Crystallization drops were set up using the sitting drop vapor diffusion method with a mosquito crystallization robot from SPT lab tech. Plate shaped crystals grew over a few days at 295 K in a 200 nl drop containing 1:1 protein to crystallization buffer 0.2 M NaCl and 20 % (w/v) PEG3350 (condition A6 from PEG/Ion screen (Hampton Research)) to which 30 nl diluted seed stock had been added. The seed stock was prepared from microcrystals grown in a drop from the SG1 (Shotgun) screen (Molecular Dimensions) condition B12 (magnesium formate dihydrate and 20 % (w/v) PEG3350) (200826 plate PI seeding A6).
