180 MICROLITERS OF ENZYME SOLUTION (6 MG/ML CK2ALPHA, 0.025 M TRIS/HCL, PH 8.5, 0.5 M NACL) WERE MIXED WITH 20 MICROLITERS OF INHIBITOR STOCK SOLUTION (0.010 M INHIBITOR THN27 IN DMSO). THIS MIXTURE WAS INCUBATED FOR 30 MIN AT ROOM TEMPERATURE. THE RESERVOIR SOLUTION OF THE CRYSTALLIZATION EXPERIMENT WAS 0.2 M AMMONIUM SULFATE, 0.1 M SODIUM CACODYLATE TRIHYDRATE, PH 6.5, 30% (W/V) PEG 8,000. PRIOR TO EQUILIBRATION THE CRYSTALLIZATION DROP WAS COMPOSED OF 10 MICROLITERS RESERVOIR SOLUTION PLUS 20 MICROLITERS ENZYME/INHIBITOR MIXTURE.
