Description：

Description：Endoglycosidase H (Endo H) is a highly specific recombinant glycosidase that cleaves within the chitobiose core of high-mannose and some hybrid N-linked oligosaccharides from glycoproteins. It hydrolyzes the β-1,4 linkage between the two N-acetylglucosamine (GlcNAc) residues, leaving a single GlcNAc attached to the asparagine residue of the peptide chain. However, Endo H does not cleave complex-type N-glycans. Protein glycosylation is a crucial post-translational modification that influences many biological functions, such as protein folding, quality control, stability, intracellular transportation, cellular and immune responses. During eukaryotic protein expression, heterogeneous glycosylation patterns can complicate purification and downstream applications. By using Leadgene® Endo H, high-mannose and hybrid N-glycans can be efficiently removed, improving protein homogeneity, facilitating purification, and enhancing protein purification efficiency, which indirectly increases the recoverable yield of proteins and antibodies.
