Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	4.6	298	Protein solution (11.0 mG/mL H8 in unbuffered 3.0MM NaN3), 2.5mL of precipitant buffer (0.1 M sodium acetate (PH 4.6), 20%(V/V) isopropanol, 0.2M CaCl2), VAPOR DIFFUSION, HANGING DROP, TEMPERATURE 298K. Soaking crystals were performed using a mother liquor (no calcium ions) with the addition of 0.5 mM AuCl3 for one week.
