Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 3.5 293 1 UL DROPS OF PROTEIN SOLUTION (7.2 MG/ML, I.E. 0.2 MM, IN 30 MM TRIS-HCL, PH 7.4, 5 MM VALPROMIDE) WERE MIXED WITH 1 UL DROPS OF RESERVOIR SOLUTION (CONTAINING 90 MM NA-HEPES, PH 7.5, 25% PEG 10, 000). Once crystals were obtained they were soaked in mother liquor at pH 3.5 prior to freezing.
