Crystallization Crystalization Experiments ID Method pH Temperature Details 1 LIPIDIC CUBIC PHASE 6 293 Protein was reconstituted in cubic phase by mixing with a 1:1.5 (w:w) protein:lipid ratio. Lipid used was a 10:1 (w:w) mix of monoolein with cholesterol. The crystal was grown in 240 mM lithium sulfate, 42% PEG 300, 1% hexanediol, and 0.1M MES pH 6.0
