WebIn contrast, HILIC (hydrophilic interaction liquid chromatography) is an attractive chromatographic technique for the analysis of these glycoconjugates. Applications usually involve detection by mass spectrometry (MS) to benefit from its high sensitivity, accuracy and resolution as well as its high throughput potential. WebThe optimized multidimensional detection offers increased confidence in glycan identification which can be further supported by an exoglycosidase digestion array (optional). Here we describe the PNGase F release of N-glycans from a typical IgG1 monoclonal antibody (mAb) with subsequent labeling with RapiFluor-MS™ for detection …
