X-RAY DIFFRACTION

Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 6.75 289 Peptide was included in protein buffer to a final molar ratio of 2:1 relative to protein. Reservoir solution contained 1.2 M sodium citrate, pH 6.75. Equal amounts (1.5 microliters) of protein (7 mg/mL) and reservoir solution were mixed and equillibrated against 500 microliters of crystallization buffer.
