How to Improve Glycoform and Glycopeptide Coverage For Mucin Preparations
See how pretreatment with a mucin-selective protease, Mucinase StcE, for tryptic-digest sample preparation of mucins may increase the number of glycopeptides and glycoforms identified from your samples.
Speeding Biosimilar Development using Glycosylation Control Technology from SAFC
The biosimilar market is expected to grow rapidly in the coming years, as many blockbuster monoclonal antibodies lose patent protection by 2020.
Peptidoglycan Structure, Biosynthesis and Function
The basic structure of peptidoglycan (PGN) contains a carbohydrate backbone of alternating units of N-acetylglucosamine (GlcNAc) and Nacetylmuramic acid, with the N-acetylmuramic acid residues cross-linked to peptides.
Glycosphingolipids
Glycosphingolipids
Glycosyltransferases
Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some
Glycoprotein Deglycosylation
Information about Glycoprotein deglycosylation. The diversity of oligosaccharide structures, both O-linked and N-linked, often results in heterogeneity in the mass and charge of glycoproteins.
Glycosyltransferases: Tools for Synthesis and Modification of Glycans
The presence of multiple functional groups and stereocenters in complex carbohydrates makes them challenging targets for the organic chemist.
Glycobiology - Carbohydrate Enzymes and Proteins
Explore our complex carbohydrate proteins, enzyme products and kits for investigating oligosaccharides, polysaccharides, and numerous additional aspects of your carbohydrate workflow.
Lipopolysaccharides for Research – Structure, Function & Applications
Explore the structure, function, and diverse applications of Lipopolysaccharides. Discover their role in bacteria, serological specificity, and research potential.
Biglycan
Biglycan is a 200-350 kDa(proteoglycan consisting of a 45 kDa core protein and two chrondroitin/dermatan sulfate glycosaminoglycan chains.
Glycosaminoglycans and Proteoglycans
There are five identified glycosaminoglycan chains (see Figure 1): Hyaluronan is not sulfated, but the other glycosaminoglycan chains contain sulfate substituents at various positions of the chain.
Glycosaminoglycan Sulfation and Signaling
Glycosaminoglycans are large linear polysaccharides constructed of repeating disaccharide units.

Glycan Sequencing Using Exoglycosidases
N-Linked Glycans Overview
N-linked glycosylation, modification, and degradation
O Linked Glycans
O-Linked glycans are usually attached to the peptide chain through serine or threonine residues. O-Linked glycosylation is a true post-translational event and does not require a consensus sequence. The most common type of O-linked glycans contain an initial GalNAc residue
O-Linked Glycan Strategies
Learn about O-linked glycan strategies, such as the actions of O-glycosidase, how to remove di and trisialylation sialic acid residues, β-linked galactose, and N-acetylglucosamine, as well as other O-glycan modifications.
Lectin Selection Guide: A Useful Guide for Selecting the Right Lectin
Find the right lectin for your research with our lectin selection guide, organized by lectin source/species, carbohydrate specificity, blood group specificity, and more.
Strategies for Deglycosylating N-Linked Glycans
Explore various strategies for deglycosylating N-linked glycans involving PNGase F, PNGase A (Glycopeptidase A), and even native and sequential deglycosylation with endoglycosidases like Endoglycosidase H, Endoglycosidase F, and exoglycosidases.
Protein Deglycosylation
Protein Deglycosylation: PNGase F Proteomics Grade, Native Protein Deglycosylation Kit, Enzymatic Protein Deglycosylation Kit, and ProteoProfile Trypsin In-Gel Digest Kit
Review of O-Linked Glycoproteins
O-Linked glycoproteins are usually large proteins with a molecular mass of >200 kDa. Glycosylation generally occurs in high-density clusters and may represent as much as 50-80% of the overall mass.

Glycoprofile™ Labeling Kits
Glycoprofile Labeling Kits for Glycan Analysis designed for efficient labeling of N-linked, O-linked and glycosylphosphatidylinositol (GPI) anchored glycans using your choice of 2-aminobenzamide (2-AB) or 2-aminobenzoic acid (anthranilic acid; 2-AA) 1,2
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
