1	VAPOR DIFFUSION, HANGING DROP	7.5	277	CRYSTALS WERE GROWN USING THE HANGING-DROP METHOD IN A NEXTAL TRAY (QIAGEN) AT 277 K AGAINST A 1 ML RESERVOIR SOLUTION CONSISTING OF 12% (W/V) PEG 2000, 0.1M BACL2, 0.1 M TRIS-HCL PH7.5. THE HANGING DROP CONTAINED 2 MICROLITRES OF CONCENTRATED ARRESTIN2 PROTEIN (BETWEEN 9-11 MG/ML IN 0.1M TRIS-HCL PH 8.5) AND 2 MICROLITRES OF RESERVOIR SOLUTION.
