1LIPIDIC CUBIC PHASE5.62930.2 %(V/V) 2-METHYL-2, 4-PENTANEDIOL (MPD), 0.1 M SODIUM CHLORIDE, 0.1 M SODIUM CITRATE/HCL PH 5.6. CRYSTALLIZED USING THE IN MESO (LIPID CUBIC PHASE) METHOD AT 20 DEGREES CELCIUS WITH THE 7.9 MONOACYLGLYCEROL (7.9 MAG) AS THE HOSTING LIPID.CRYSTALLIZATION WAS SET UP BY INCUBATING 20 MICROLITERS OF LIPID CUBIC PHASE WITH 400 MICROLITERS OF PRECIPITANT SOLUTION IN COUPLED SYRINGES.
