Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	10.5	298	100mM Tris-base at pH 10.5 and 8% PEG3K. Apo crystals were obtained by soaking the crystals in a mother liquid containing 10mM EDTA. The cobalt derivative was obtained by back soaking the apo-crystals in a mother liquid containing 10mM cobalt ions, VAPOR DIFFUSION, HANGING DROP, temperature 298K
