Abstract
A NUMBER of electrolytes, which are in common use in the fractionation of proteins, have been studied for their effect on choline- and ali-esterase of the housefly. The substrates were acetylcholine and ethylbutyrate, respectively. Enzyme activity was measured by a pH-titrimetric method using barbitone-HCl (pH 7) as buffer.
