Overview
CMP-N-Acetylneuraminic Acid is an activated sugar, and can be used for in vitro glycoengineering of glycoproteins, e.g. therapeutic proteins.
CMP-NANA is a sodium salt, provided as a white, lyophilized substance.
Benefits of using in vitro glycoengineering to modify glycosylation of therapeutic proteins:
  • Time- and cost-saving generation of glycan variants to develop improved drugs
  • Optimized glycosylation without compromising other CQAs or product yield
  • Improved lot-to-lot consistency to reduce risk of product quality variation and resulting delays
  • Generation of glycoprofiles which may not otherwise be generated
  • Streamlined analytics in comparability studies
+-
Application
Incubation of CMP-NANA and α-2,6-Sialyltansferase or α-2,3-Sialyltansferase with a glycoprotein leads to increased sialylation of the glycoprotein.
