1	VAPOR DIFFUSION, HANGING DROP		277.15	We soaked these crystals with BTA and TA by carrying out the following steps: (i) We prepared soaking solutions containing 1.32 M sodium citrate, 1 mM ZnSO4, 100 mM Tris-HCl (pH 7.8), and 5 mM ligand. (ii) We combined 4 uL of soaking solution and 1-2 crystals of HCAII within a drop on the surface of a reservoir cover (EasyXtal CrystalSupport, Qiagen). (iii) To a clear plastic reservoir in a 15-reservoir plate (EasyXtal, Qiagen), we added 1 mL of soaking solution (without ligand present). We attached the reservoir cover to the reservoir and left the entire setup at 4 deg C for 1 week.
