New Materials for the Separation and Enrichment of N-Glycopeptides/Glycoproteins

蛋白质糖基化在调节各种复杂的生物过程中,如分子识别、免疫应答和蛋白质折叠等起着至关重要的作用。由于糖肽/糖蛋白在复杂生物样品或临床样品中丰度较低,进行糖蛋白组学分析前往往需要进行目标蛋白的分离富集。研究开发具有高效糖蛋白分离富集能力的新型材料对糖蛋白/糖肽的研究具有重要意义。近年来报道了许多新型糖蛋白分离富集材料,如有机高分子材料、生物基材料、新型有机骨架材料和新型功能复合材料等。这些材料因其结构、生物相容性和理化性质等特点,从不同层面推动了糖蛋白分离富集技术的发展。本文就目前国内外有关糖肽/糖蛋白分离富集的新型材料进行了总结和讨论,并对其未来发展提出展望。

Protein glycosylation plays a crucial role in regulating various complex biological processes, such as molecular recognition, immune response, and protein folding. Since glycopeptides / glycoproteins are less abundant in complex biological samples or clinical samples, separation and enrichment of target proteins are often required before glycoproteomics analysis. Research and development of novel materials with high-efficiency glycoprotein separation and enrichment ability are of great significance for the study of glycoprotein/glycopeptide. In recent years, many new glycoprotein separation and enrichment materials have been reported, such as organic polymer materials, bio-based materials, new organic framework materials and new functional composite materials. Due to their structure, biocompatibility and physical and chemical properties, these materials have promoted the development of glycoprotein separation and enrichment technology from different levels. In this paper, the new materials related to the separation and enrichment of glycopeptide / glycoprotein at home and abroad are summarized and discussed, and the future development is proposed.
