Glycan libraries are becoming popular products for a variety of applications including their use as standards for analytical carbohydrate chemistry to confirm structural analyses or as standards for monitoring separations of oligosaccharides.  NatGlycan can produce custom glycan libraries of your choice in quantities that can ensure their long-term availability for your glycomics work. We currently have structurally defined high mannose and pauci-mannose N-glycans available as AEAB derivatives for mass spectrometry standards that permit the identification of specific fragmentation patterns and of unique fragments for structural definitions. These and any series of glycans can be provided as free glycans or as 2AB or 2AA derivatives for use as HPLC standards.
