UDP-GlcNAz (UDP-N-azidoacetylglucosamine)

UDP-GlcNAz is an analogue of UDP-GlcNAc with an N-azidoacetyl group. This azide handle supports bioorthogonal labeling after incorporation into an appropriate acceptor. It is chemically distinct from UDP-6-azido-GlcNAc, which carries the azide at C6 rather than on the N-acyl group. Application focus Use in glycosyltransferase substrate studies and click-based detection workflows with an experimentally validated enzyme and acceptor. 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.
