ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7.5	295	A three-fold excess of the inhibitor was added to the DES-GLA-FACTOR XA. the protein was then concentrated to 12-17 MG/ML. Crystals were grown using 2 UL of complex with 2 UL of reservoir containing 15-21% PEG1500 and 10 MM CACL2, pH 7.5, VAPOR DIFFUSION, HANGING DROP, temperature 295K
