X-RAY DIFFRACTION 7.0 ? THE METHYL MERCURY ADDUCT WAS OBTAINED BY BRINGING STOCK SOLUTION OF VIRUS (3.5% TCV (W/V) IN 0.01% SODIUM AZIDE,) TO 6 EQUIVALENT METHYL MERCURY/PROTEIN SUBUNIT BY ADDITION OF 15 MILLIMOLAR-METHYL MERCURY NITRATE AND INCUBATING FOR 1 H. CRYSTALLIZATION WAS THEN INITIATED BY ADDITION OF AN APPROXIMATELY EQUAL VOLUME OF SATURATED SODIUM CITRATE (PH 7.0) AND ALLOWED TO PROCEED UNDISTURBED FOR 2 TO 4 MONTHS. THE OPTIMUM CONCENTRATION OF SODIUM CITRATE REQUIRED TO PRODUCE LARGE CRYSTALS VARIED FROM EXPERIMENT TO EXPERIMENT BUT WAS GENERALLY IN THE RANGE 42 TO 46% SATURATED.
