1 | BATCH MODE | 298 | The RIIb (R230K):C apo complex was crystallized in 20%PEG8000, 8% Ethylene Glycol, 20mM MESpH7.5 HEPES . To make CaATP binding holoenzyme crystals, the apo holoenzyme crystals were soaked with 20%PEG8000, 8% Ethylene Glycol, 20mM MESpH7.5 HEPES, 5mM CaCl2 and 1mM ATP at pH5.8 solution overnight |
