Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7.6	293	Drop were prepared by mixing 1ul of protein solution (~10 mg/ml in 20 mM HEPES pH 7.5, 100 mM NaCl, and 20 uM PLP buffer ) with 1ul of reservoir solution. The reservoir contained 0.7-1M Succinic acid pH 7.6. Crystals formed after 48h.
