Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5.5	293	Crystallization: 0.1-0.5mM CuSO4, 1.25 mM NiCl2, 100mM sodium cacodylate pH=5.5, 3mM sodium azide and 5% glycerol. The crystal was first soaked in 5mM ascorbic acid and then soaked in 300mM NaNO2 (with 5mM ascorbic acid) for 13 hours at RT., VAPOR DIFFUSION, HANGING DROP, temperature 293K
