ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP		293	10 mg/mL TcDH in 25 mM borate buffer, pH 9.5 was mixed with 0.17 M ammonium acetate, 0.085 M sodium citrate, pH 5.6, 25.5% w/v PEG 4000, 15% glycerol. To increase copper incorporation, powder of CuCl was added to drops with crystals 30-40 min prior to harvesting. Sodium cyanate solution was added to the drop with crystals to the final concertation of ~100 mM at the same time as CuCl was added.
