1	VAPOR DIFFUSION, SITTING DROP		289	CRYSTALS WERE GROWN IN SITTING DROPS CONTAINING EQUAL AMOUNTS (200-400 NL) OF PROTEIN (15 MG/ML IN 20 MM HEPES PH 7.4, 120 MM NACL, 4 MM DTT) AND RESERVOIR SOLUTION (100 MM BIS TRIS PROPANE, 200 MM SODIUM MALONATE, 20% (W/V) PEG 3350) AND EQUILIBRATED AGAINST 80 UL OF RESERVOIR SOLUTION AT 16C. CRYSTALS WERE CRYOPROTECTED BY BRIEF IMMERSION (5-60 S) IN RESERVOIR SOLUTION SUPPLEMENTED WITH 25% GLYCEROL AND WERE RAPIDLY CRYOCOOLED IN LIQUID N2 OR A 100 K STREAM OF N2 GAS.
