1	VAPOR DIFFUSION, SITTING DROP	5.5	293.15	90 MIKROLITER ENZYME STOCK SOLUTION (6 MG/ML IN 500 MM NACL, 25 MM TRIS/HCL, PH 8.5) WAS MIXED WITH 10 MIKROLITER INHIBITOR STOCK SOLUTION (10 MM INHIBITOR IN DMSO). THIS MIXTURE WAS INCUBATED FOR 30 MIN AT ROOM TEMPERATURE. THE RESERVOIR SOLUTION OF THE CRYSTALLIZATION EXPERIMENT WAS 4.4 M NACL, 0.1 M CITRIC ACID, PH 5.5. PRIOR TO EQUILIBRATION THE CRYSTALLIZATION DROP WAS COMPOSED OF 1 MIKROLITER RESERVOIR SOLUTION PLUS 1 MIKROLITER ENZYME/INHIBITOR MIXTURE.,VAPOR DIFFUSION, SITTING DROP, TEMPERATURE 293.15K
