QA-Bio also supplies a wide variety of qualitative and quantitative glycan standards and glycoprotein standards to be used during glycoprofiling. All are produced at the highest quality and purity levels.
Glycans – >98% purity by NMR and HPLC
Glycan Libraries – Fetuin, IgG, Glucose homopolymer ladder(GHP)
Quantitative Standards – determined by qNMR and qMonosaccharide analysis
Glycoprotein Standards – Fetuin, IgG
Monosacharrides – Monosaccharide mixtures, sialic acids
Alpha-Galactose – both labeled and unlabeled
Our glycan and glycoprotein standards have been used in FDA and EMEA approved assays since 2002, by pharmaceutical and biotech companies around the world. They are qualified by MS, HPLC, and NMR analysis to meet our rigorous standards of quality and contain no salts or other additives that may interfere with advanced analytical techniques such as mass spectrometry which require the highest levels of purity.
We have a complete line of glycan products for analytical markers including both N-linked and O-linked glycans, IgG and fetuin glycoproteins, IgG and fetuin libraries. They are commonly used in biopharmaceutical labs as markers and reference compounds in HPLC, HILIC, MS, HPAEC, and MALDI-TOF analytical techniques.
