title: Fluorometric assay for polyamines in urine and tissues using electrophoresis on Titan III cellulose acetate.
abstract: A simple, rapid assay method for polyamines (putrescine, spermidine, and spermine) in urine and tissues using electrophoresis on Titan III cellulose acetate was developed. In this procedure, polyamines are preliminarily extracted from a hydrolysate of urine or from supernatants of tissue homogenates by use of a Bio-Rex 70 minicolumn. After electrophoretic separation, polyamines are fluorometrically detected by the reaction with o-phthalaldehyde and 2-mercaptoethanol. Six extracts and two external standards of polyamines can be separated and detected in 11 min on a cellulose acetate strip. This method permits the determination of polyamines in a range of 0.1 mM (25 pmol) to 1.0 mM (250 pmol).
