ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP		298	initial crystal hits were grown in 27.5% (w/v) PEG 10,000, 0.1 M MES, pH 6.50, at an equal ratio of protein to crystallization solution. Microseeding was used to obtain isolated crystals in 10% (w/v) PEG 10,000 and 0.1 MES, pH 6.50 at a protein concentration of 5 mg/mL, VAPOR DIFFUSION, HANGING DROP, temperature 298K
