摘要:
In this study, assisted by affinity-guided DMAP strategy, we developed a novel F-19-modified lectin as a biosensor for specific detection and imaging of glycoproteins. Exploited the large chemical shift anisotropy property of F-19 nuclei, glycoproteins detected by our F-19-biosensor are signatured by broadened peaks in F-19 NMR, hence enabled the distinction between glycoproteins and small molecule saccharides. Such signal on/off switching was also applied to glycoprotein imaging by F-19 MRI. (C) 2011 Elsevier Ltd. All rights reserved.
