This includes kits for release and labelling of monosaccharides or sialic acids, N- or O-glycan labelling kits and glycan clean-up/ purification and enrichment systems. We also offer system suitability standards and qualitative and quantitative controls, High-performance liquid chromatography (HPLC) and Ultra High-performance liquid chromatography (uHPLC) columns and buffers offering a one stop shop for all your glycan analysis needs!

Glycan Release

A range of Ludger enzymes (Endoglycosidases and Exoglycosidases) and Ludger Liberate™ (chemical release) standalone products and kits are available at Ludger for release of N- and O-linked glycans from glycoprotein therapeutics, cell lines, biological fluids, or any glycoprotein moieties of interest to you.

Clean up

LudgerClean™ range of products includes individual cartridges, spin-columns and 96-well plates that can reliably remove contaminants from variety of complex mixtures. These include protein removal, desalting and removal of detergents and post-labelling cleanup of LudgerTag™ fluorophores and chromophores to suit your need.


LudgerTag™ range includes kits covering all areas of glycan labelling. We provide quantitative monosaccharide and quantitative sialic acid release and labelling kits designed to satisfy the regulatory requirements for biopharmaceutical realisation. We also provide labelling kits with various fluorescent tags and MS-active tags for glycan and glycopeptide labelling as well as a glycan derivatisation kit.

Standards & Controls

Ludger Standards and Controls include high-quality glycoproteins, glycopeptides, unlabelled N- and O-glycan standards, as well as quantitative glycan and glycopeptide standards for different applications including the analysis of sialic acids, monosaccharides, glycan profiling and characterisation. We also offer a wide selection of standards fluorescently labelled with 2-aminobenzamide (2-AB), 2-AA (2-aminobenzoic acid), procainamide, and 8-aminopyrene-1,3,6-trisulfonic acid (APTS) to support your analytical workflows.


LudgerSep™ range offers a variety of HPLC and UHPLC columns and buffers to support reliable, quantitative, and robust analysis of released glycans, sialic acid and monosaccharide analysis.
