ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	9	293.15	Protein: 2.5 mg/ml NEGR1 in 10 mM HEPES, pH 8.0, 150 mM NaCl. Reservoir Solution: 20% (w/v) PEG 3350, 0.1 M Tris pH 9.0, 0.2 M MgCl2, 0.6 M NaI. Crystallization Drop: 1 micro-Liter NEGR1 + 1 micro-Liter Reservoir Solution Single crystals were obtained via microseeding, and their size improved to ~600 x 200 micro-meters by macroseeding. Crystals harvested from the crystallization drops were cryo-protected in reservoir solution containing 20% (v/v) MPD and then flash cooled by plunging into liquid nitrogen
