A fluorometric, reversed-phase high-performance liquid chromatography (RP-HPLC) method that allows quantitation of low levels of alloxan has been described. The method involved derivatization of alloxan with 500-200,000-fold excess of 1, 2-phenylenediamine (PD) in 0.1 M acetate buffer, pH 4.5 for 15 min at room temperature. The fluorescent product alloxazine (excitation: 382 nm; emission: 435 nm) was then analyzed by RP-HPLC using an Eclipse XDB-C18 (4.6 x 150 mm) column and a mobile phase consisting of 0.1% trifluoroacetic acid in 15/85 (v/v) acetonitrile/water at a flow of 1 mL/min (injection volume: 20 microL). The method is robust, and as low as 0.1 pmol of the analyte could be successfully detected and quantified. Following a minimal pre-treatment such as ultrafiltration (molecular weight cut-off 5000 Da) or protein precipitation using perchloric acid, acetonitrile, or phosphotungstic acid, the method is suitable for analysis of alloxan in complex physiological fluids (e.g. fetal bovine serum) and tissue homogenates (e.g. heart and kidney). The method has been rigorously evaluated and adapted in the laboratory for routine analysis and determination of alloxan added to cell cultures.
