Product Description


Butyrylcholinesterase (BChE) belongs to the same structural class of proteins as acetylcholinesterase (AChE). The 440kDa tetrameric glycoprotein is predominantly found in blood, kidneys, intestine, liver, lung, heart and the central nervous system. BChE preferentially acts on butyrylcholine, but also hydrolyzes acetylcholine. Alzheimer’s disease appears to be associated with decreased acetylcholinesterase activity and an increase in Butyrylcholinesterase activity. BChE activity, therefore, has potential applications as a biomarker for progression or as a target for future therapies.

Key Benefits

  • Measure BChE activity as fluorescent readout; endpoint or kinetically.
  • Run serum, plasma, CSF or cell/tissue lysates as samples.
  • Sensitive – measure <0.02mU/ml of BChE activity.

Assay Principle

The Fluoro Butyrylcholinesterase Activity kit is designed to quantitatively measure butyryl- cholinesterase (BChE) activity in a variety of samples such as serum or plasma, cell and tissue lysates. The kit utilizes a non- fluorescent molecule, the Thiol Detection Reagent, that covalently binds to the thiol product of the reaction between the BChE Substrate and BChE in the standards or samples, yielding a fluorescent product read at 510 nm in a fluorescent plate reader with excitation at 390 nm.
