Drops containing 3.0 L of enzyme solution [5.0 mg/mL AKR1D1, 2.0 mM NADP+, 0.5 mM finasteride, 10.0 mM Tris (pH 7.4)] and 4.0 L of precipitant buffer [0.1 M TRIS-HCl (pH 7.0), 10-20% (wt/vol) PEG 4000, 10% iso-propanol] were equilibrated against a 1 mL reservoir of precipitant buffer. Crystals of the AKR1D1-NADP+-finasteride, complex were soaked for 24 hours in the same mother liquor solution augmented with 2.0 mm NADP+, 2.0 mM finasteride and 30% iso-propanol, VAPOR DIFFUSION, HANGING DROP
