Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	8	293	Best crystals were obtained at 20 degrees from 1:1 microL drops with complex solution (8mg/mL in 5mM Tris HCl pH8, 5mM calcium chloride, 0.02% sodium azide) and 0.4M sodium/potassium tartrate as reservoir solution. Crystals were cryo-protected by immersion in cryo-solution (0.32M sodium/potassium tartrate, 25%[v/v] glycerol), VAPOR DIFFUSION, SITTING DROP, temperature 293K
