Abstract
Affinity chromatography has been used to purify acetylcholinesterase both from the electric tissue of Electrophorus electricus and from bovine erythrocyte membranes. For this purpose, several specific enzymic inhibitors of each protein were synthesized and joined covalently to an insoluble support resin. AchE is selectively retained by such inhibitor-resins when highly impure solutions are chromatographed upon them. After removal from the resin, both enzymes are electrophoretically homogeneous and they may be recovered in yields of 75% or more.
