1 | 10% PEG 6000, 10 MM POTASSIUM PHOSPHATE, 100 MM POTASSIUM CHLORIDE, 3 MM SODIUM DITHIONITE, 10 MG/ML DEOXYHB, PH 7.0, BATCH, TEMPERATURE 298K, 1 ATM N2. EXPOSING DEOXY CRYSTAL TO LIGAND: A DEOXY CRYSTAL WAS SOAKED (UNDER 1 ATM NITROGEN) IN SUBSTITUTE MOTHER LIQUOR CONTAINING 13% PEG 6000, 10 MM POTASSIUM PHOSPHATE (PH 7.0), 100 MM POTASSIUM CHLORIDE. THE CRYSTAL WAS THEN EXPOSED TO AIR AT 298K AND DATA WAS COLLECTED AT 298K. |
