1VAPOR DIFFUSION, SITTING DROP293.1590 MIKROLITER ENZYME STOCK SOLUTION (6 MG/ML IN 500 MM NACL, 25 MM TRIS/HCL, PH 8.5) WAS MIXED WITH 10 MIKROLITER 4P STOCK SOLUTION (10 MM 4P IN DMSO). THIS MIXTURE WAS INCUBATED FOR 30 MIN AT ROOM TEMPERATURE. THE RESERVOIR SOLUTION OF THE CRYSTALLIZATION EXPERIMENT WAS 4.2 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/4P MIXTURE., VAPOR DIFFUSION, SITTING DROP, TEMPERATURE 293.15K
