Acetylcholinesterase (eel)

Acetylcholinesterase (AChE) is a highly conserved homotetrameric carboxylesterase that is composed of four ~70 kDa subunits, each containing a single active site. In the electric eel (E. electricus), AChE is highly expressed in the electric organs at the posterior innervated membrane, where it hydrolyzes acetylcholine to acetate and choline to terminate synaptic transmission between electromotor neurons and electrocytes. AChE has commonly been used in biomedical research in assays, such as ELISA, for the detection or quantification of target molecules. It has also been used in the detection of organophosphate and carbamate pesticides due to their ability to inhibit AChE activity. Cayman's Acetylcholinesterase (eel) protein can be used for ELISA, enzyme activity assay, and Western blot applications.
