1 | 8 | 20MG/ML UOX IN 50 MM TRIS-ACETATE PH 8.0 SATURATED WITH 9-METHYL URIC ACID UNDER ANAEROBIC CONDITIONS RESERVOIR: 8% PEG 8000, 50 MM TRIS-ACETATE PH 8.0 CRYSTALLIZATION WAS CARRIED OUT ANAEROBICALLY. CRYSTALS WERE INCUBATED WITH A RESERVOIR SOLUTION ENRICHED BY 10 MM H2O2 AND 20% GLYCEROL TO GENERATE THE PEROXIDE |
