  Synthesis of multivalent N-acetyl lactosamine modified quantum dots for the study of carbohydrate and galectin-3 interactions

  摘要：

  Ternary core/shell CdSeS/ZnS-QDs coated with N-acetyl lactosamine was prepared as a fluorescent probe to study the interactions of N-acetyl lactosamine and galectin-3. The synthesis of N-acetyl lactosamine was achieved through the 'azidoiodoglycosylation' method. The amount of ligand coated on QDs was determined by H-1 NMR and ICP-OES. The interactions between carbohydrates and galectin-3 were measured using SPR. The results revealed that the affinity of galectin-3 with di- and multivalent N-acetyl lactosamine increased 20 and 184-fold, respectively. The prepared glyco-QDs could be used as an efficient fluorescent probe to study carbohydrates and galectin-3 interactions. (C) 2012 Elsevier Ltd. All rights reserved.
