18.5INITIAL, TWINNED CRYSTALS WERE GROWN BY MIXING EQUAL VOLUMES OF PROTEIN SOLUTION (8 MG ML IN WATER) AND RESERVOIR (25 % PEG 3350, 0.2 M LI2SO4, 0.1 M TRIS-HCL, PH 8.5). THESE CRYSTALS WERE USED TO SEED PREEQUILIBRATED DROPS CONTAINING 4 MG ML PROTEIN, 20 % PEG 3350, 0.05 M LI2SO4, 0.09 M TRIS-HCL, PH 8.5.
