1	VAPOR DIFFUSION, HANGING DROP	7.2		CRYSTALS WERE GROWN OVER A PERIOD OF ELEVEN MONTHS USING THE HANGING DROP VAPOR DIFFUSION METHOD BY EMPLOYING THE CONDITIONS 5 (MICRO)L OF THE PROTEIN (20 MG/ML OF THE PROTEIN), 5MM CACL2, 50MM TRIS BUFFER, PH 7.2 AND 2.5 (MICRO)L OF 75% MPD IN THE DROPLET. THE RESERVOIR CONTAINED (55%) OF MPD., vapor diffusion - hanging drop
