ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5	291	Crystallization solution: 50 mM di-Ammoniumhydrogen citrate, PEG6000= 5 % (m/V) DTT= 5.15 g/L NADP+= 0.66 g/L and Human Aldose Reductase= 15 mg/ml. Afterwards the crystals were soaked into 120 mM di-Ammoniumhydrogen citrate pH 5.0 25% (m/V) PEG6000 saturated with the inhibitor. The well solution was 120mM di-Ammonium hydrogen citrate with 20% PEG6000 pH 5.0, VAPOR DIFFUSION, HANGING DROP, temperature 291K
