Glycan Labeling Kits

Acetic Acid – Promotes acid catalyzed ring opening of the glycan reducing terminus prior to the formation of an imine intermediate between the sugars and the unprotonated form of the dye

Fluorescent Dye – The comprehensive range of LudgerTag dyes include 2-AB, 2-AA, Procainamide, DMB, and APTS to cover different types of glycoanalyses by HPLC, CE, and MS.

DMSO – An anhdrous solvent used to dissolve all the components of the reductive amination labeling reaction.

Sodium Cyanoborohydride or Non-Toxic 2PB – This reductant stabilizes the imine produced by the reaction of the dye and glycans to produce stable fluorescently labeled glycan

Procainamide Image

Procainamide Labeling Kit

Procainamide labeling permits glycan identification by either mass spectrometry or UHPLC. Because of its improved ionisation efficiency compared to 2-AB labelling, it can permit identification of minor glycans (1% relative peak area) by ESI-MS.

permethylation kit image

Permethylation Kit

This kit is used for the permethylation of glycans. Permethylation stabilizes sialic acids for MALDI mass spectrometry analysis, and aids linkage analysis studies (MALDI-MS, ESI-MS).

- Improves and enhances ionization efficiency of glycans on mass spec
- Increased glycan hydrophobicity enables LC-MS analysis
- Relative and absolute quantitation can be performed
- Stabilizes the sialic acid moieties
- Easier determination of branching and glycosidic linkage positions
- Enables detection of both neutral and acidic glycans in positive ion mode

2-AB labeling kit image

2-AB Labeling Kits

2-AB (2-aminobenzamide) is one of the most widely used fluorescent labels for glycosylation analysis. The LudgerTag 2-AB Labeling Kit includes all the reagents required to label up to 30 glycans samples.Photo Guide of the Procedure View product documentation as PDF View Certificate of Analysis as PDFTwo kits are available which differ in the type of reductant supplied: sodium cyanoborohydride or non-toxic 2-picoline borane.Part Number    Reductant LT-KAB-A2       Sodium Cyanoborohydride LT-KAB-VP24   2-Picoline Borane
2-AA labeling kit image

2-AA Labeling Kit

2-AA (2-aminobenzoic acid) is considered by many to be a superior replacement for 2-AB in most types of complex glycan analysis. 2-AA labeling is reported to have a higher fluorescence and gives higher labelling efficiencies than 2-AB.View protocol picture guide as a PDF View product documentation as PDF View Certificate of Analysis as PDFTwo kits are available which differ in the type of reductant supplied: sodium cyanoborohydride or non-toxic 2-picoline borane.Part Number    Reductant LT-KAA-A2       Sodium Cyanoborohydride LT-KAA-VP24   2-Picoline Borane
