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.
This quantitative glycopeptide standard was developed for use during the sialic acid or monosaccharide release and labeling process. This will enable you to check the efficiency of glycan release, labeling, and recovery.

The Fetuin Glycoprotein Standard was developed for use as a positive control during glycan release and labeling (particularly for DMB sialic acid analysis). Fetuin exists in a variety of glycoforms containing bi-, tri-, and tetraantennary N-linked oligosaccharides with variable sialylation, as well as O-linked glycans.
