Invitrogen™ Butyrylcholinesterase Fluorescent Activity Kit
Description
Includes
96-well plates, standard, detection reagent, assay buffer, substrate, and lot-specific technical data sheet.
The Butyrylcholinesterase Fluorescent Activity research-use-only kit is a fluorescent activity assay designed for the quantification and detection of butyrylcholinesterase activity in serum and plasma samples.
This complete, ready-to-use kit includes black 96-well plate(s), butyrylcholinesterase standard (200 mU/mL), butyrylcholinesterase substrate, and other components to perform the assay. A fluorescence 96-well microplate reader capable of reading fluorescent emission at 510 nm, with excitation at 390 nm, is required for use of this kit.
Performance characteristics
• Assay type: fluorescent activity kit
• Sample types: serum and plasma samples
• Sensitivity: 0.018 mU/mL
• Standard curve range: 0.3–20 mU/mL
• Reactivity: species independent
Background
Butyrylcholinesterase (BChE) belongs to the same structural class of proteins as acetylcholinesterase (AChE). The 440 kDa tetrameric glycoprotein is predominantly found in blood, kidneys, intestine, liver, lung, heart, and the central nervous system. Many species, such as human, horse, and mice exhibit high BChE activity in plasma, whereas rats have higher acetylcholinesterase activity in plasma1. BChE preferentially acts on butyrylcholine, but also hydrolyzes acetylcholine. This assay has been validated for serum, EDTA and heparin plasmas from a variety of species.

Assay principle
The Butyrylcholinesterase Activity kit is designed to quantitatively measure butyrylcholinesterase (BChE) activity in a variety of samples. A human BChE standard is provided to generate a standard curve for the assay and all samples should be read off the standard curve. The kit utilizes a proprietary non-fluorescent 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. The kit is suitable for measuring BChE activity in appropriately diluted serum or plasma from a number of species. It will also measure BChE in extracted tissue samples, CSF, and cell lysates.
BChE unit definition
One unit will hydrolyze 1.0 μmol of butyrylcholine to choline and butyrate per minute at pH 8.0 and 37°C.
