ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	6.5	293	Droplets were prepared by mixing 1l of protein solution and 1l of reservoir solution (0.1M calcium acetate, 0.1M sodium cacodylate, 10% PEG8000, pH 6.5) supplemented with one fifth volume of 10% PEG3350 as an additive and were equilibrated, typically, for one week against 1ml of reservoir solution., VAPOR DIFFUSION, SITTING DROP, temperature 293K
