1	VAPOR DIFFUSION, SITTING DROP			CRYSTALS WERE GROWN IN SITTING DROPS CONTAINING 200 NL PROTEIN (5.8-6.8 MG/ML) AND 100 NL RESERVOIR SOLUTION (20-18% W/V PEG 3350, 0.10-0.09 M BIS-TRIS PROPANE PH 7.5, 0.2-0.18 M SODIUM CITRATE) EQUILIBRATED AGAINST 95 UL RESERVOIRS AT 20.5 C. CRYSTALS WERE CRYOPROTECTED BY SOAKING IN MOTHER-LIQUOR SUPPLEMENTED WITH 20-25% GLYCEROL FOR 1-10 MIN.
