Description

A rapid microassay is described for the measurement of biogenic amines using an isocratic HPLC system with electrochemical detection. Catecholamines, indoleamines and their major metabolites were extracted with 150 microliters of perchloric acid from brain tissue punches (less than 250 micrograms) using a simple one-step sample preparation method. These compounds were separated on a short (80 mm) column with 3 microns particle size packing, and electrochemically detected within a total run time of less than 6 minutes. Detection limit sensitivity was approximately 2-5 pg. This method, detailed in an easy-to-follow description, reduces assay time, minimizes the possibility for errors, maximizes efficiency, and requires only standard HPLC equipment and supplies.
