摘要: 利用自组装的毛细管电泳-激光诱导荧光装置,研究了多种寡糖-8-氨基芘-1,3,6-三磺酸(寡糖-APTS)衍生物的分离.考察了电泳介质、浓度及pH对寡糖-APTS衍生物分离的影响,在酸性和碱性条件下,分别实现了痕量寡糖标准品及葡聚糖水解产物的高效分离

关键词: APTS, 寡糖, 葡聚糖, 毛细管电泳-激光诱导荧光

Abstract: Reducing oligosaccharides, after reductive amination, were separated and detected as their APTSderivatives by capillary electrophoresis with laser-induced fluorescence. Brief optimization studies have also been performed with respect to CEseparation conditions of oligosaccharides. The oligosaccharide ladders were analyzed in an acidic phosphate-tris buffer(pH2.5) or in the alkaline borate buffer. Acid hydrolysis products of dextran T-40 labeled with APTSwere also successfully mapped.

Key words: 8-Aminopyrene-1,3,6-trisufonate(APTS), Oligosaccharide, Dextran, Capillary electropho-resis with laser-induced fluorescence detection
