172932.3 M AMMONIUM SULFATE 50MM POTASSIUM PHOSPHATE PH 7.0 CRYSTALS WERE REDUCED USING 20MM SODIUM DITHIONITE. THE CRYSTAL WAS TRANSFERRED TO A SOLUTION CONTAINING 2.3 M AMMONIUM SULFATE, 50 MM PHOSPHATE BUFFER PH 7 AND 15 % GLYCEROL. CO WAS INTRODUCED UNDER 15 ATM PRESSURE FOR 20 MINUTES AT -20 DEGREES.
