1	VAPOR DIFFUSION, SITTING DROP	8.5	298	VAPOUR-DIFFUSION SITTING DROP, AT 298 K. 10.0 MG/ML OF PROTEIN SOLUTION CONTAINING 5 MM ATP WAS MIXED WITH RESERVOIR SOLUTION CONTAINING 0.35 M AMMONIUM SULFATE AND 0.1 M TRIS-HCL BUFFER, PH 8.5. BEFORE THE DATA COLLECTION THE CRYSTAL WAS SOAKED IN SOLUTION CONTAINING 0.35 M MAGNESIUM CHLORIDE INSTEAD OF AMMONIUM SULFATE. THE CRYOPROTECTANT CONTAINED 33% OF ETHYLENE GLYCOL IN ADDITION TO MAGNESIUM CHLORIDE, BUFFER AND ATP
