Clinical Glycomics Employing Graphitized Carbon Liquid Chromatography–Mass Spectrometry

Clinical Glycomics Employing Graphitized Carbon Liquid Chromatography–Mass Spectrometry

Glycoconjugates and free glycan are involved in a variety of biological processes such as cell-cell interaction and cell trafficking. Alterations in the complex glycosylation machinery have been correlated with various pathological processes including cancer progression and metastasis. Mass Spectrometry (MS) has evolved as one of the most powerful tools in glycomics and glycoproteomics and in c...

Glycomics Using Mass Spectrometry

Mass spectrometry (MS), which has advanced rapidly in recent years, is expected to become the tool of choice for high-throughput analysis of relationships between structures and functions of glycans. The structural analysis of glycans using MS employs a number of methods for pretreatment, derivatization, and interpretation. However, since none of these are universally applicable, researchers ha...

Characterization of Polymer Carbon Sieves, Graphitized Polymer Carbons and Graphitized Carbon Blacks for Sample Preparation Applications

Self-assembled chains of graphitized carbon nanoparticles

We report a technique which allows self-assembly of conducting nanoparticles into long continuous chains. Transport properties of such chains have been studied at low temperatures. At low bias voltages, the charges are pinned and the chain resistance is exponentially high. Above a certain threshold VT , the system enters a conducting state. The threshold voltage is much bigger than the Coulomb ...

Oligosaccharide Substrate Preferences of Human Extracellular Sulfatase Sulf2 Using Liquid Chromatography-Mass Spectrometry Based Glycomics Approaches

Sulfs are extracellular endosulfatases that selectively remove the 6-O-sulfate groups from cell surface heparan sulfate (HS) chain. By altering the sulfation at these particular sites, Sulfs function to remodel HS chains. As a result of the remodeling activity, HSulf2 regulates a multitude of cell-signaling events that depend on interactions between proteins and HS. Previous efforts to characte...
