X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.0	293	A racemic mixture of L-lacticin Q and D-lacticin Q at 27 mg/mL concentration was mixed 1:1 with 4.0M sodium formate precipitant condition pH 7.0 in a 1 microlitre sitting drop. Crystals were submerged in 2.0M Lithium sulfate cryoprotectant and flash frozen in liquid nitrogen during harvesting.
