Glycans are usually fluorescently tagged by reductive amination for analytic tools. However, free reducing glycan regeneration is sometimes important and necessary for further structural or functional studies. Here, we introduce a new method for efficiently removing fluorescent tags from glycoconjugates by a simple treatment with Oxone. This method is proven to be fast and general after being tested on a series of common saccharides and widely used tags. We successfully achieved -glycopeptide synthesis by using the regenerated glycans.
糖通常通过还原胺化反应进行荧光标记,以便于分析工具使用。然而,对于进一步的结构或功能研究,有时需要对游离还原糖进行再生。在此,我们介绍了一种通过使用 Oxone 简单处理从糖缀合物中有效去除荧光标记的新方法。该方法在一系列常见的糖和广泛使用的标记物上进行测试后,被证明快速且通用。我们成功地使用再生糖实现了 -糖肽的合成。
