1	Vapor diffusion, sitting drop *	6.8 *		MOLECULE: RECOMBINANT CASEIN KINASE I DELTA. CRYSTALS WERE GROWN BY THE SITTING DROP TECHNIQUE, MIXING 3 MICROLITER OF PROTEIN SOLUTION WITH 3 MICROLITER OF RESERVOIR SOLUTION. THE PROTEIN SOLUTION CONSISTED OF 14 MG/ML PROTEIN IN 50 MM TRIS-HCL (PH=7.5), 1 MM EDTA, 5 MM DTT, 0.2 M NACL, 2.5 MM BETA-OCTYL GLUCOSIDE. THE RESERVOIR SOLUTION CONTAINED 15% PEG 3400, 50 MM SODIUM CITRATE, 50 MM DIBASIC POTASSIUM PHOSPHATE, (PH=6.8). ROOM TEMPERATURE.
