(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. |
