Characterization of Glycan Structures of Chondroitin Sulfate-Glycopeptides Facilitated by Sodium Ion-Pairing and Positive Mode LC-MS/MS
Purification and liquid chromatography-tandem mass spectrometry (LC-MS/MS) characterization of glycopeptides, originating from protease digests of glycoproteins, enables site-specific analysis of protein N- and O-glycosylations. We have described a protocol to enrich, hydrolyze by chondroitinase ABC, and characterize chondroitin sulfate-containing glycopeptides (CS-glycopeptides) using positive...
متن کاملComparisons of Caenorhabditis Fucosyltransferase Mutants Reveal a Multiplicity of Isomeric N-Glycan Structures
Recent studies have shown a remarkable degree of plasticity in the N-glycome of the model nematode Caenorhabditis elegans; ablation of glycosylation-relevant genes can result in radically altered N-glycan profiles despite only minor biological phenotypic effects. Up to four fucose residues and five different linkages of fucose are known on the N-glycans of C. elegans. Due to the complexity in t...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولthe effect of consciousness-raising activities on learning grammatical structures by iranian guidance school efl learners
abstract the first purpose of this study was to investigate the effect of consciousness-raising (c-r) activities on learning grammatical structures (simple present tense in this case) by iranian guidance school efl learners. the second one was to investigate the effect of gender on learning the simple present tense through c-r activities and tasks. finally, this study aimed to investigate the ...
Prediction of Glycan Structures from Microarray Data Prediction of Glycan Structures from the Glycan Related Microarray Expression Profiles
Glycans, which attach to some lipids and to Asn/Ser/Thr residues of proteins, draw attention as the third biological chains next to DNA and protein, since they play a key role in embryogenesis, immunity and diseases. Glycans consist of carbohydrate sugars and their derivatives such as glucose (Glc), mannose (Man), N-acetyl-glucosamine (GlcNAc) and sialic acid (Neu5Ac), and form linear and branc...
