Continuous Fluorometric Assays for Acetylcholinesterase Activity and Inhibition with Conjugated Polyelectrolytes

Quick but sensitive: A super-quenched fluorogenic complex of a cationic acetylcholine (ACh) derivative with an energy-acceptor tag and an anionic water-soluble conjugated polymer forms the basis of a highly effective fluorescence turn-on assay for studying the enzyme kinetics and inhibition of acetylcholinesterase (AChE; see schematic representation of the assay). FRET=fluorescence resonant energy transfer. Supporting information for this article is available on the WWW under http://www.wiley-vch.de/contents/jc_2002/2007/z701724_s.pdf or from the author.
