N2 - 2-Amino-3-phenylpyrazine is found to be a sensitive fluorescence labeling reagent for saccharides with a reducing end. The labeled monosaccharides show strong fluorescence under various pH conditions, and could be analyzed by both HPLC and HPCE techniques. Laser induced fluorescence detection is also applicable. Following derivatization with 2-amino-3-phenylpyrazine, six monosaccharides are separated by an HPCE system within 23 min in the calibration range of 5 or 10 fmol to 5 pmol (injection amount). The within-day and day-to-day precisions of the monosaccharide determinations are 3.83-4.86% (RSD) and 3.37-4.56% (RSD), respectively. This method was successfully applied to the determination of component monosaccharides in a glycoprotein, bovine serum fetuin.
