X-RAY DIFFRACTION 6.5 ? COCRYSTALLISATION WITH 20MM OF KCLO4 (PERCHLORATE) IN 200MM OF DDNAPA (IE PROTEIN) WHICH HAD BEEN REDUCED BY DITHIONITE IN ANAEROBIC CONDITIONS AND THEN AIR REOXIDISED. THE SAMPLE WAS LEFT AT ROOM TEMPERATURE FOR SEVERAL MONTHS BEFORE SETTING UP CRYSTALLISATIONS IN 0.1M MES, PH 6.5, 8% PEG 8000
