Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5.5	293	Crystallization: 0.1-0.5mM CuSO4, 1.25mM NiCl2, 100mM sodium cacodylate pH=5.5, 3mM sodium azide and 5% glycerol. The crystal was first soaked in 1mM substrate (Ac-3,5-diI-YG) for 1 hour and then soaked in 300mM NaNO2/1mM substrate for 14 hours at 293K., VAPOR DIFFUSION, HANGING DROP
