Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6.5	277	2 uL of 5.6 mg/mL resorufin ligase containing 1 mM resorufin sulfamoyladenosine, 1 mM Mg(OAc)2, and 1 mM dithiothreitol mixed with 2 uL of precipitant solution (11% PEG 20,000, 0.15 M MES:NaOH, pH 6.5). Dark, and red colored crystalline plates appeared after ~ 5 days. Crystals were looped and washed through a cryoprotection solution of 80% precipitant solution (12% PEG 20,000, 0.2 M MES:NaOH, pH 6.5) and 20% glycerol. Crystals were then cryocooled by direction submersion into liquid nitrogen.
