1 | VAPOR DIFFUSION, SITTING DROP | 7.8 | 291.15 | His6-tagged GgUOX at approx. 22 mg/ml in 50 mM Tris-HCl pH 8.0, 10 mM NaCl, 1 mM TCEP-HCl was incubated with a 20-fold molar excess of AZA. Crystals were obtained by mixing the protein with 8% PGA-LM, 0.3M KBr, 0.1M Tris-HCl pH 7.8 using a 1:1 ratio. Crystals were then transferred into cryoprotective solutions supplemented with 100 mM H2O2 and devoid of the TCEP-HCl reducing agent for approximately 15 minutes prior to cryocooling in liquid nitrogen. |
