Identification and quantification of N-linked oligosaccharides released from glycoproteins: an inter-laboratory study.
As characterization of glycosylation is required for the licensing of recombinant glycoprotein therapeutics, technique comparability must be assessed. Eleven UK laboratories (seven industrial, two regulatory or government, two academic) participated in an inter-laboratory study to analyze N-glycans present in four mixtures prepared by PNGase F cleavage of commercial glycoproteins: human alpha1-...
متن کاملConcise Review: Cell Surface N‐Linked Glycoproteins as Potential Stem Cell Markers and Drug Targets
: Stem cells and their derivatives hold great promise to advance regenerative medicine. Critical to the progression of this field is the identification and utilization of antibody-accessible cell-surface proteins for immunophenotyping and cell sorting-techniques essential for assessment and isolation of defined cell populations with known functional and therapeutic properties. Beyond their util...
متن کاملQuantitative Mass Spectrometric Analysis of Glycoproteins Combined with Enrichment Methods
Mass spectrometry (MS) has been a core technology for high sensitive and high-throughput analysis of the enriched glycoproteome in aspects of quantitative assays as well as qualitative profiling of glycoproteins. Because it has been widely recognized that aberrant glycosylation in a glycoprotein may involve in progression of a certain disease, the development of efficient analysis tool for the ...
متن کاملSelective identification and differentiation of N- and O-linked oligosaccharides in glycoproteins by liquid chromatography-mass spectrometry.
A mass spectrometry method has been developed for selective detection of glycopeptides at the low (< or = 25) picomole level during chromatography of glycoprotein digests and for differentiation of O-linked from N-linked oligosaccharides. The technique involves observation of diagnostic sugar oxonium-ion fragments, particularly the HexNAc+ fragment at m/z 204, from collisionally excited glycope...
متن کاملA Mass Spectrometric-Derived Cell Surface Protein Atlas
Cell surface proteins are major targets of biomedical research due to their utility as cellular markers and their extracellular accessibility for pharmacological intervention. However, information about the cell surface protein repertoire (the surfaceome) of individual cells is only sparsely available. Here, we applied the Cell Surface Capture (CSC) technology to 41 human and 31 mouse cell type...
