Affinity column purification of BChE The 1200-fold purified BChE from QFF was loaded onto a 150 ml affinity column at a flow rate of 350 ml per hour. The column was washed with 2 L of 20 mM potassium phosphate, 1mM EDTA pH 7.0 followed by 2 L of 0.2 M NaCl in buffer to elute contaminants. The graph shows elution of BChE from procainamide-Sepharose with 1 M NaCl in pH 7 buffer.
