THEREAFTER, LIPIDIC-SPONGE PHASE INITIATING SOLUTION (20% JEFFAMINE M600, 1M HEPES PH=8.0, 0.7M (NH4)2SO4 AND 2.5% 1,2,3-HEPTANETRIOL) WAS ADDED IN A RATIO OF 1 TO 4 (V/V) AND EQUILIBRATED UNTIL PHASE SEPARATION HAS OCCURRED. THE UPPER LIPIDIC-SPONGE PHASE WAS HARVESTED AND 1UL WAS USED AS A PRECIPITANT SOLUTION TOGETHER WITH 1UL OF 25 MG/ML PROTEIN SOLUTION IN A HANGING-DROP, VAPOUR-DIFFUSION EXPERIMENT. TO IMPROVE CRYSTAL QUALITY 1UL OF ADDITIVE 1M TRI-NA-CITRATE HAS BEEN ADDED TO THE CRYSTALLIZATION DROP.
