we have purified completely the principal asymmetric ( `` '' heavy '' '' ) form of acetylcholinesterase ( ac-choease ; ec 3.1.1.7 ) from chick muscle ( i.e. , the synaptic form in the twitch muscle fibers ) by using a monoclonal antibody that recognizes acchoease but not pseudocholinesterase ( choease ; cholinesterase , ec 3.1.1.8 ) .
