Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION	7.5	287	8mg/ml protein in 20mM Hepes (pH7.5), 100mM NaCl, 5% w/v glycerol, 1mM EDTA, and 1mM DTT. Equal volume of protein and precipitant (20mM MES (pH 6.5), 17% w/v PEG10K) were equilibrated by vapor diffusion at 14C. Crystals were soaked with the inhibitor ZPR. Cryosolution is precipitant plus 5% more PEG10K and 20% w/v glycerol, VAPOR DIFFUSION, temperature 287K
