ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7	298	CRYSTALLIZATION CONDITIONS: CRYSTALS OF RECOMBINANT WT TTR WERE OBTAINED FROM PROTEIN SOLUTIONS AT 5 MG/ML (IN 100 MM KCL, 100 MM PHOSPHATE [PH 7.4], 1 M AMMONIUM SULFATE) EQUILIBRATED AGAINST 2 M AMMONIUM SULFATE IN HANGING DROP EXPERIMENTS. THE TTR LIGAND COMPLEXES WERE PREPARED FROM CRYSTALS SOAKED FOR 2 WEEKS WITH A 10-FOLD MOLAR EXCESS , PH 7.00, VAPOR DIFFUSION, HANGING DROP, TEMPERATURE 298K , VAPOR DIFFUSION, HANGING DROP
