GlycoProfile^™ 2-AA Labeling Kit

• UNSPSC Code: 12352200
• EC Number: 204-287-5
• NACRES: NA.32

Description

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

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.

GlycoProfile^™ 2-AA Labeling Kit has been used in the labeling of fluorescently derivatized N-glycans from chinese hamster ovary CHO cells.
