Hilic standard
WebGlycation is an important post-translational modification that is linked to diabetes, cataract, Alzheimer’s, Rheumatoid arthritis and Parkinson’s disease. 1 This reaction occurs between a reducing sugar and a primary amine at the N-terminus of protein or the sidechain of Lysine residues. Ultimately this interaction leads to advanced glycation end products (AGEs) that … WebA hydrophilic interaction liquid chromatography (HILIC)–ultra high-pressure liquid chromatography (UHPLC) coupled with tandem mass spectrometry (MS/MS) method was …

WebA hydrophilic interaction liquid chromatography (HILIC)–ultra high-pressure liquid chromatography (UHPLC) coupled with tandem mass spectrometry (MS/MS) method was developed and applied to profile metabolite changes in human Huh-7 cells exposed to the potent aryl hydrocarbon receptor (AHR) ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). … WebBoth columns have the same zwitterionic HILIC packing material, but packed into either stainless steel hardware or PEEK-lined stainless steel hardware. Sharper peaks mean both better resolution and better sensitivity. Lastly, all hope is not lost if all you have is a standard, stainless steel-based LC.
