Detection and quantification of leached ethylene glycol in biopharmaceuticals by RP-UHPLCEthylene glycolLeachablesReversed-phase ultrahigh-performance liquid chromatographySchotten–Baumann reactionBiopharmaceuticals are in direct contact with different plastic materials, which can contribute to process-related ...
Here, we describe the use of reverse phase-ultra high performance liquid chromatography (RP-UHPLC) in combination with non-reductive 2-aminobenzamide (2-AB) labeling. Non-reductive 2-AB labeling enabled separation of C4-oxidized gluco-oligosaccharides from their non-oxidized counterparts. Moreover,...
Our results show that RP-UHPLC-UV-ESI-MS in combination with non-reductively 2-AB labeling is a suitable technique for the separation and identification of LPMO-generated C4-oxidized gluco-oligosaccharides. 展开 关键词: dimethyl sulfoxide (PubChem CID: 679) deuterated sodium borohydride (PubChem...
