O-Glycosylation Site Occupancy Analysis


O-glycosylation of proteins is a common modification with diverse structures and functions. Due to the clinical and biopharmaceutical importance, it is necessary to comprehensively characterize O-glycoproteins including the determination of glycan composition, sequence and attachment site. Site-specific O-glycosylation analysis is key to explore structure-function relationships of glycoproteins, such as in the context of antigenicity and disease progression. Mass spectrometry (MS)-based methods have proven to be the core technique in site-specific O-glycosylation analysis.

Overview of O-Glycosylation Site Occupancy Analysis Service

Because the addition of O-glycans affects intracellular processes including protein folding and maturation, O-glycosylation site occupancy must be measured quantitatively to unravel the macroheterogeneity in glycoprotein populations, which is important for quality control of glycoproteins. Quantitation of O-glycosylation site occupancy can be applied to the fields of diagnostics, glycotherapeutics, and glycolengineering. At Creative Proteomics, we provide a reliable and affordable O-glycosylation site occupancy analysis service for academics, biotechnology, and pharmaceutical communities.

Mass spectrometry (MS) has emerged as a powerful tool for comprehensive analysis of glycoproteins. Creative Proteomics utilizes the most advanced MS platforms and other proteomic techniques to provide the accurate, reliable O-linked glycosylation site occupancy analysis service for identification of truly O-glycosylated peptides.
