1	VAPOR DIFFUSION, HANGING DROP		293	The crystals were obtained using a protein concentration of 16 mg/mL and in 0.1 M Cadmium chloride hydrate, 0.1 M Sodium acetate trihydrate (pH 4.6), 30% (v/v) Polyethylene glycol 400. Crystal quality was enhanced in presence of 2.0 M Sodium Thiocyanate or 1.0 M Sodium Bromide.
