Method	pH	Temprature	Details
X-RAY DIFFRACTION	8	291	COX-2 protein reconstituted with a 2-fold molar excess of heme in phosphtate buffer, pH 6.7, 100 mM NaCl, 1.2% (w/v) -OG, and 0.1% NaN3, and 10-fold molar excess of inhibitors from 25 mM DMSO stocks were added to protein samples. Mixing 3.5 uL of the protein-inhibitor complex with 3.5 uL crystallization solution containing 50 mM EPPS, pH 8.0, 120 mM MgCl2, 22-26% PEG MME-550 against reservoir solutions comprised of 50 mM EPPS pH 8.0, 120 mM MgCl2, 22-26% PEG MME-550
