Robustness of RapiFluor-MS N-Glycan Sample Preparations and Glycan BEH Amide HILIC Chromatographic Separations

Robustness of RapiFluor-MS N-Glycan Sample Preparations and Glycan BEH Amide HILIC Chromatographic Separations

11 Jan 2016

N-glycosylation of proteins is routinely characterized and monitored because of its significance to the detection of disease states and the manufacturing of biopharmaceuticals. Glycosylation profiles are most often assessed by means of released glycan analyses, wherein samples are often prepared by techniques that are notoriously time-consuming or lead to compromises in MS sensitivity. This application note discusses the attributes of RapiFluor-MS based sample preparation and the corresponding HILIC-based LC analyses.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.

It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

GlycobiologyGlycobiology encompasses research into the biological functions, synthesis and structures of glycans, including glycoproteins, glycolipids, proteoglycans and free oligosaccharides. Mass spectrometers and their software are commonly used in the study of glycobiology, along with structure predicting tools, chromatography and NMR.Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.GlycansBiopharmaceuticalsBiopharmaceuticals are proteins and other compounds (such as nucleic acids) produced by living organisms that have uses as therapeutics or for in vivo diagnostics. The most well known example of a biopharmaceutical product, and the first to be approved for therapeutic use, was recombinant human insulin.HILICGlycosylationProtein Quantification
