Analysis Note
The activity obtained using acetylcholine as substrate is 30-100 times that obtained with butyrylcholine, using acetylcholinesterase from electric eel.
Application
Acetylcholinesterase human has been used:
- as a standard protein to measure protein levels acetylcholinesterase AChE-R and AChE-S
- to stimulate human fibroblasts
- to study its in vitro catalytic activity and to determine the effects of metals, H2O2 and OH radicals on the activity
Biochem/physiol Actions
Acetylcholinesterase (AChE) is regarded as a biomarker in neurotoxicity. It is a modulator of nitric oxide signal transduction pathway and marker of membrane integrity and aging. AChE, hydrolyzes choline esters. It terminates the impulse transmission at cholinergic synapses. AChE does this by rapid hydrolysis of the neurotransmitter acetylcholine (ACh) to acetate and choline. AChE inhibitors prevent the cholinesterase enzyme from breaking down ACh and increases the level and duration of the neurotransmitter action.
Major degradative enzyme for acetylcholine in vivo. Converts acetylcholine + H2O to choline + acetic acid.
General description
Acetylcholinesterase (AChE) is a serine hydrolase, which belongs to the carboxyl esterase family of enzymes. AChE is localised at neuromuscular junctions and cholinergic brain synapses.
Other Notes
One unit will hydrolyze 1.0 μmole of acetylthiocholine to thiocholine and acetate per minute at pH 8.0 at 37 °C.
Physical form
This product is supplied as a lyophilized powder. Lyophilized from 0.22 μm filtered solution in 50mM phosphate buffer pH8.

Essential oils (EOs) are often the source of insecticidal substances of high efficiency and low toxicity. From gas chromatograph-mass spectrometer, column chromatography, and nuclear magnetic resonance spectra analyses, twenty terpenes were identified from the EOs of Artemisia nakaii. These comprised

Despite extensive efforts in the development of drugs for complex neurodegenerative diseases, treatment often remains challenging or ineffective, and hence new treatment strategies are necessary. One approach is the design of multi-target drugs, which can potentially address the complex nature
