凝集素在糖蛋白研究中的作用日益重要。在这里,我们报告了一种基于金属螯合聚合物与凝集素的共价连接的糖谱方法,用于基于电感耦合等离子体-质谱仪的分析。标记的凝集素能够区分共价附着在微滴定板上的糖蛋白,它们的结合可以直接用电感耦合等离子体质谱定量。由于每种结合物含有不同的稀土元素,因此分析可以以单一或多重的方式进行,并且可以很容易地细化为许多不同的分析格式。
Lectins have been increasingly important in the study of glycoproteins. Here we report a glycoprofiling method based on the covalent attachment of metal-chelating polymers to lectins for use in an ICP-MS-based assays. The labeled lectins are able to distinguish between glycoproteins covalently attached to a microtiter plate and their binding can be directly quantified by ICP-MS. Since each conjugate contains a different lanthanide, the assays can be conducted in a single or multiplex fashion, and may be readily elaborated to many different assay formats.
