Method pH Temprature Details
X-RAY DIFFRACTION 4.2 293 A solution of protein at 1mM was incubated with 5mM cellohexose for 4 hours at room temperature. The mixture was screened using a TTP Labtech Mosquito and MRC SD-2 plates 200 nL protein 200 nL reservoir, 50 microliter total reservoir. Crystals formed in condition B6, 40% ethanol, 10% PEG1000, 0.1M phosphate citrate buffer pH 4.2. Crystals were exposed to vapor from 45% ethanol for 30 seconds prior to plunge cooling in liquid nitrogen.
