1	VAPOR DIFFUSION, SITTING DROP	7.7		PROTEIN WAS CRYSTALLIZED BY VAPOR DIFFUSION USING THE SITTING-DROP METHOD. THE DROP CONTAINED 5-7 MG/ML PROTEIN, 20 MM TRIS/CL AT PH 7.7, 100MM LICL, 20MM MGSO4, 1.2% BETA-D-OCTYLGLUCOPYRANOSIDE AND 6-9% PEG-2000. THE CONCENTRATION OF PEG IN THE RESERVOIR WAS 12-15%. 2M SUCROSE WAS ADDED TO THE DROP FOR COCRYSTALLIZATION.
