Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	7.5	291	Sitting drop 96 MRC2 well plates using a mosquito crystal robot (TTP Labtech). Crystals were obtained by mixing 0.25 ul of E coli AGPase_R130A at 6.3 mg/ml in 50 mM Tris-HCl pH 7.5, 100 mM NaCl with 0.25 ul of mother liquor containing 14% polyethylene glycol 3.350, 140 mM magnesium formate, 30% ethylene glycol. Crystals grew in 13 days and were frozen under liquid nitrogen.
