X-RAY DIFFRACTION	4.6	293	PURE PROTEIN EXTENSIVELY DIALYSED AGAINST SODIUM ACETATE BUFFER AT PH 4.6 WAS USED IN THE CRYSTALLIZATION TRIALS. CRYSTALS WERE OBTAINED BY THE BATCH METHOD USING 4-5 MG/ML PROTEIN IN 0.05 M SODIUM ACETATE BUFFER CONTAINING 0.2 M SODIUM CHLORIDE, 1.5 MM LACTOSE AND 0.05 %SODIUM AZIDE. THE PRECIPITANT USED WAS PEG 8000, A SOLUTION OF WHICH IN THE SAME BUFFER WAS ADDED TO A FINAL CONCENTRATION OF ABOUT 12%. THE TUBES WERE LEFT UNDISTURBED FOR ABOUT TWO WEEKS, BY WHICH TIME CRYSTALS SUITABLE FOR DATA COLLECTION GREW., SMALL TUBES, temperature 293K
