Abstract
The activity-pH relationship for choline esterase from horse serum, gastric mucosa of the pig, and cat brain was investigated, and an optimum was observed at pH 8.5 in each case.
A micro method for the determination of choline esterase was developed capable of measuring the hydrolysis down to the order of that given by 1 x 10–8 mol of ester.
