Determination of acetylcholine and choline in microdialysates from spinal cord of rat using liquid chromatography with electrochemical detection.
A method for the determination of acetylcholine and choline in microdialysates from rat spinal cord has been developed using liquid chromatography, enzyme-catalysed post-column derivatization and electrochemical detection. The sensitivity required was achieved by a certain degree of miniaturization, careful temperature control and a slight modification of the amperometric detector. Determinations were performed on 5-microliter samples.
