Charged glycans
WebGet industry-leading, ultra-high resolution of labeled and native glycans for structural characterization and quantification using the Thermo Scientific™ GlycanPac™ AXR-1 LC Columns. This high-performance, silica-based chromatography column achieves mixed-mode separation using a combination of charge, isomer structure, and size. WebGlycan charges are usually due to sialic acids, however they can also result from sulphation or phosphorylation of monosaccharide building blocks. Biopharmaceuticals often contain two main types of sialic acid; N -acetyl-neuraminic acid (Neu5Ac) and N …
Charged glycans

Glycosaminoglycans vary greatly in molecular mass, disaccharide structure, and sulfation. This is because GAG synthesis is not template driven, as are proteins or nucleic acids, but constantly altered by processing enzymes. GAGs are classified into four groups, based on their core disaccharide structures. Heparin/heparan sulfate (HSGAGs) and chondroitin sulfate/dermat… WebWikipedia
