General description

The GlycoProfile™ labeling kits are designed for efficient labeling of N-linked, O-linked, and glycosyl­phosphatidyl­inositol (GPI) anchored glycans with either 2-aminobenzamide (2-AB) or 2-aminobenzoic acid (anthranilic acid; 2-AA). These small fluorophores increase the spectral absorption of glycans, improving the detection of labeled glycans by HPAE (high-performance anion exchange chromatography), HPLC, and ESI-MS (electrospray mass spectroscopy) methods. Binding is robust and the resulting dye-glycan conjugates are stable, with no degradation during post-labeling analysis.

Application

GlycoProfile™ 2-AB Labeling Kit has been used for the labelling of N-linked glycans from human IgG, Bovine fetuin, and human epididymis protein 4. It has also been used for labelling free oligosaccharides from mouse spleen.
While 2-AB is slightly less sensitive than 2-AA, it is suitable for downstream glycan analysis by HPAE, HPLC and ESI-MS. Although suitable for the same applications, 2-AA is better suited for SDS-PAGE.

Legal Information

Labeling of glycans with 2-AB is covered under US Patent No. 5,747,347 and its foreign equivalents.
GlycoProfile is a trademark of Sigma-Aldrich Co. LLC

Glycan Labeling

Structural modifications of proteins are essential to living cells. When aberrantly regulated they are often the basis of disease. Glycans are responsible for much of the structural variation in biologic systems, and their representation on cell surfaces is commonly called the “glycome.”

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
