1 | VAPOR DIFFUSION, HANGING DROP | 7 | CRYSTALS OF WT HUMAN TTR- LIGAND COMPLEXES WERE OBTAINED AT ROOM TEMPERATURE IN ABOUT ONE WEEK BY CO-CRYSTALLIZATION, USING THE HANGING-DROP VAPOR DIFFUSION METHOD. THE PROTEIN (5 MG/ML), IN 20 MM SODIUM PHOSPHATE, PH 7, WAS INCUBATED WITH A FOUR-FOLD MOLAR EXCESS OF LIGANDS SOLUBILIZED IN DMSO. DROPS WERE FORMED BY MIXING EQUAL VOLUMES OF THE SOLUTION CONTAINING LIGAND-TTR COMPLEXES AND OF THE RESERVOIR/PRECIPITANT SOLUTION (2.2 M AMMONIUM SULPHATE, 0.1 M KCL, 0.03 M SODIUM PHOSPHATE, PH 7.0). |
