Methacholine Chloride 149-174 acetylcholinesterase (Cartwright blood group) Homo sapiens 100-120 6840242-2 1983 It is possible to measure AChE activity in human plasma in spite of high butyrylcholinesterase activity if acetyl-beta-methylcholine is used as the substrate and butyrylcholinesterase is inhibited by iso-OMPA.
