UDP-6-azido-galactose (UDP-6-N3-Gal)

UDP-6-azido-galactose is an analogue of UDP-galactose with an azide handle at C6. It is intended for glycan labeling research in systems that accept the modified nucleotide donor. The azide can be paired with an appropriate alkyne reagent for detection after transfer. Research context Published living-cell glycoengineering work paired UDP-6-N3-Gal with the N. meningitidis β1,4-galactosyltransferase NmLgtB. Validate activity with the transferase and acceptor used in your own experiment. Product selection and documentation Reference identifiers describe the labelled chemical form; they do not establish the counterion or hydration of a particular lot. Confirm the supplied form, assay, purity method and storage conditions on the lot certificate of analysis. Use the lot-specific formula weight when preparing molar solutions. Experimental planning Enzyme acceptance depends on the transferase, acceptor and reaction conditions. Validate the donor with your enzyme system; nucleotide sugars should not be assumed to enter cells simply because related monosaccharide precursors do.
