Method pH Temprature Details
X-RAY DIFFRACTION 4.6 292 A racemic mixture of L-Aureocin A53 and D-Aureocin A53 at 40 mg/mL concentration was mixed 1:1 with 0.2 M ammonium sulphate, 0.1 M sodium acetate and 24.5% PEG 4000 v/v precipitant condition, pH 5.6 in a 1 microlitre sitting drop. Crystals were submerged in 20% PEG 400 in the precipitant solution as cryoprotectant and flash frozen in liquid nitrogen during harvesting.
