| 1 | 7 | THE CRYSTALLISATION MIXTURE CONSISTED OF 10-12% (W/V) PEG3350, 100-200MM IMIDAZOLE, PH 7.0, 5-10% (V/V) ISOPROPANOL, AND 1% (V/V) DMF OR 3% (V/V) T-BUTANOL. THE PROTEIN SOLUTION WAS DILUTED BY 40 - 60% REMARK 280 WITH THE CRYSTALLISATION BUFFER, GIVING A FINAL REMARK 280 CONCENTRATION OF 4-6 MG. ML-1 IN SUSPENDED DROPS OF VOLUME REMARK 280 2 - 3 PERCENT. | ||
