Radiometric Assay of FAAH Activity

Methods Mol Biol. 2023:2576:241-247. doi: 10.1007/978-1-0716-2728-0_20.

Abstract

Fatty acid amide hydrolase (FAAH) is an intracellular enzyme responsible for the hydrolysis of endogenous anandamide (AEA), a reaction that terminates the biological effects of this lipid mediator. The final products of AEA cleavage are arachidonic acid and ethanolamine. In the method described herein, FAAH activity is measured through the use of the radioactive substrate [14C-ethanolamine]-AEA and subsequent quantification of the reaction product [14C]-ethanolamine.

Keywords: AEA; Arachidonic acid; Bioactive lipids; Endocannabinoids; Enzyme; Ethanolamine; FAAH.
