Crystallization

Crystalization Experiments
Method Vapor Diffusion Hanging Drop
pH 7
Temperature 298.0
Details 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
