Analysis of carbohydrates

摘要

The present invention discloses a method of separating or distinguishing carbohydrate substances. More particularly the method includes using fluorescent labeling reagents which have a positive charge when bound to a carbohydrate, involves separating the labeled carbohydrate substances, such as by performing electrophoresis to cause differential migration of different labeled carbohydrate substances, or by isoelectric focusing in a pH gradient. The fluorescent labeling reagents are preferably cyanine dyes.
