Hilic glycan
WebGlycosylation of biotherapeutics can impact drug safety, efficacy, and stability, therefore it is often designated as a critical quality attribute (CQA) in biopharmaceutical development. 1 Given its sensitivity to upstream processing conditions, glycosylation also serves as a key indicator of process stability and robustness. 2 In addition to the … WebBecause glycans are very hydrophilic (polar), a common separation mode employs amide-HILIC columns; as exemplified by the Thermo Scientific™ Accucore™ 150-Amide-HILIC column, that resolves glycans by hydrogen-bonding, producing a size and composition-based separation.
