Abstract

A method of oligosaccharide analysis involving controlled fragmentation resulting from enzymatic digestion is presented. The principle involves generating a set of fragments from the original oligosaccharides, characterizing them in terms of their hydrodynamic volumes, determining their molar proportions, and identifying the oligosaccharides by comparison with a computer-generated data base. Experimentally, this technique involves incubation of aliquots of a sample with a set of defined mixtures of exoglycosidases followed by pooling of the products and a single analysis on the product pool. This method has several practical advantages over current techniques, including speed and the ability to use smaller amounts of starting material. The detection of the intensity-versus-hydrodynamic volume profile is limited only by the specific activity of the labeling method. The ability to perform the enzyme digestions is limited by the individual Km values of the enzymes.

摘要

本文介绍了一种涉及酶消化产生可控片段的寡糖分析方法。其原理包括从原始寡糖生成一组片段,根据它们的流体力学体积对其进行表征,确定它们的摩尔比例,并通过与计算机生成的数据库进行比较来鉴定寡糖。在实验中,该技术涉及将样品的等分试样与一组确定的外切糖苷酶混合物一起孵育,然后合并产物并对产物池进行单一分析。与当前技术相比,该方法具有几个实际优势,包括速度快以及能够使用较少量的起始材料。强度与流体力学体积曲线的检测仅受标记方法的比活性限制。进行酶消化的能力受酶的各个 Km 值限制。
