The peptidase activity of human serum butyrylcholinesterase: studies using monoclonal antibodies and characterization of the peptidase.

Purified human serum butyrylcholinesterase, which exhibits cholinesterase, aryl acylamidase, and peptidase activities, was cross-reacted with two different monoclonal antibodies raised against human serum butyrylcholinesterase. All three activities were immunoprecipitable at different dilutions of the two monoclonal antibodies. At the highest concentration… CONTINUE READING
