钴酞菁功能化聚合物整体柱的制备及用于转铁蛋白糖肽的富集
Preparation of cobalt phthalocyanine functionalized polymer monolith and application to enrichment of transferrin glycopeptides
摘要
Abstract
Poly(glycidyl methacrylate-ethyleneglycol dimethacrylate)(Poly(GMA-EDMA)) monolith functionalized with cobalt phthalocyanine tetracarboxylic acid(CoPcTc)was pre-pared. The monolith was used for transferrin(Tf)glycopeptide enrichment. By taking advan-tage of hydrogen bonds between isoindole subunits of phthalocyanine and glycans and coordina-tion interaction between cobalt and glycopeptides,the monolithic material was efficient and selective. After enrichment of transferrin through the functionalized monolith,17 glycopeptides were identified by electrospray ionization quadrupole time-of-flight mass spectrometry. When the concentration of transferrin was reduced to 8.8×10-10mol/L,three glycopeptides could still be obtained. The present method has great potential for trace sample analysis.关键词
