Incorporation of Unnatural Sugars

Incorporation of Unnatural Sugars

Similar to unnatural amino acids, sugars with bioorthogonal handles can be incorporated into glycoproteins as chemical reporters. Various types of azido sugars have been successfully used to facilitate the labeling of surface glycoproteins on bacteria, mammalian cells and viruses.1 Compared to chemical modifications, incorporation of sugars and the subsequent bioorthogonal reactions are less invasive and yield robust. At Profacgen, we offer the reliable strategies for each specific research request including:

  • Supply of commonly used azido sugars;
  • Custom synthesis of specific unnatural sugars;
  • Bioorthogonal labeling of glycoproteins on bacteria and mammalian cells;
  • Cell lines designed for superior viral expression;
  • Bioorthogonal labeling of viral surface proteins;
  • Comprehensive analysis of labeled glycoproteins.
