Electrochemical detection of human brain transmitter amino acids by high-performance liquid chromatography of stable o-phthalaldehyde-sulphite derivatives
Abstract
A simple, sensitive, reliable and reproducible isocratic HPLC technique for the measurement of OPA/sulphite derivatives of human brain amino acid neurotransmitters is described. This employs a sample preparation that is also compatible with the concurrent determination of monoamines and their metabolites on a separate HPLC system. The method has been applied to the determination of GABA and glutamate in brain tissue taken post-mortem from patients with Huntington's disease and control subjects.
