Method	pH	Temprature	Details
X-RAY DIFFRACTION	5.2	?	LYOPHILIZED D121N RNASE A WAS DISSOLVED IN UNBUFFERED WATER TO A CONCENTRATION OF 60MG/ ML. CRYSTALLIZATION WAS PERFORMED IN SMALL SILICONIZED TUBES USING THE BATCH METHOD. A SOLUTION (25UL) OF THE ENZYME WAS MIXED WITH AN EQUAL VOLUME OF 95% (V/V) 2-METHYL-2,4-PENTANEDIOL IN 0.10 M MES BUFFER, PH 5.2. CRYSTALS APPEARED WITHIN SEVERAL MONTHS., batch method
