1	liquid-liquid diffusion		298	TRI-PEPTIDE WAS CO-CRYSTALLIZED WITH [E296Q]LTA4H BY LIQUID-LIQUID DIFFUSION IN MELTING-POINT CAPILLARIES. A TRIS-BUFFERED (10 mM, PH 7.5) SOLUTION OF PROTEIN AND TRIPEPTIDE, MOLAR RATIO 1:10 (~70 MICROM PROTEIN), WAS LAYERED ON THE PRECIPITATE SOLUTION CONTAINING 28% (WEIGHT/VOLUME) POLYETHYLENE GLYCOL (MW 8000), 50 mM NA ACETATE, 100 mM IMIDAZOLE, PH 6.8, AND 5 MM YBCL3. CRYSTALS WERE ADDITIONALLY SOAKED IN SOLUTIONS WITH INCREASED TRI-PEPTIDE CONCENTRATION PRIOR TO DATA COLLECTION., liquid-liquid diffusion, temperature 298K
