title: High-performance liquid chromatographic separation of biogenic polyamines using 2-(1-pyrenyl)ethyl chloroformate as a new fluorogenic derivatizing reagent.
abstract: The application of a new fluorogenic pre-column derivatizing reagent, 2-(1-pyrenyl)ethyl chloroformate (PEOC), is reported for the separation and detection of biogenic polyamines using column liquid chromatography. The development of the method included the optimization of excitation and emission wavelengths, efficient gradient programming, derivatization temperature, time, and pH. Minimum detection limits, linear ranges, reproducibility, and recovery from analyzed samples were determined. The procedure was applied to hydrolyzed serum samples taken from healthy individuals and cancer patients. Separation of PEOC-derivatized polyamines from the serum hydrolysis by-products was successful and detection limits were more favorable than those previously reported for 9-fluorenyl-methyl chloroformate-derivatized polyamines.
