General Description
Dextran is a polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(166) linkages. The remaining (163) linkages account for the branching of dextran. Conflicting data on the branch lengths implies that the average branch length is less than three glucose units. However, other methods indicate branches of greater than 50 glucose units exist. Native dextran has been found to have a molecular weight (MW) in the range of 9 million to 500 million. Lower MW dextrans will exhibit slightly less branching and have a more narrow range of MW distribution. Dextrans with MW greater than 10,000 behave as if they are highly branched. As the MW increases, dextran molecules attain greater symmetry. Dextrans with MW of 2,000 to 10,000, exhibit the properties of an expandable coil. At MW below 2,000, dextran is more rod-like. The MW of dextran is measured by one or more of the following methods: low angle laser light scattering, size exclusion chromatography, copper-complexation and anthrone reagent colorometric reducing-end sugar determination and viscosity.
Application
FITC-dextran is used in cardiovascular, microcirculation, perfusion, cell monolayer and cell membrane permeability research as fluorescent flux tracer compound that supports the measurement of processes such as blood flow, membrane damage, vascular drainage and renal elimination. Small FITC-dextrans are also used to measure processes such as endocytosis and cell junction permeability. Fluorescein-dextran, 500 kDa, may be used as a cerebral spinal fluid (CSF) tracer. FITC-dextran-500 may be used to study endothelial or epithelial monolayer porosity, apical-basolateral movements within cell layers and cell junction permeability. FITC-dextran is used extensively in microcirculation and cell permeability research utilizing microfluorimetry. FITC-dextran has been used to study plant cell wall porosity and capillary permeability. Plasma proteins have been shown not to bind to FITC-dextran. Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals.

| 英文名称 | 2-AB Chitotriose – Quantitative |
一般描述
The 2-AB labeled chitotriose standard is a fluorescently tagged linear tri-N-acetylglucosamine quantitative standard. The standard has been accurately dispensed from a bulk solution the concentration of which has been determined by quantitative NMR.
The chitotriose quantatative standard is also available as an unlabeled glycan and 2-AA labeled.
Accurate Quantity The bulk chitotriose concentration value was used to determine the amount of sample to be dispensed per vial to obtain 100 pmol of chitotriose per vial. Once dispensed the amount of chitotriose per vial is determined by monosaccharide analysis. The dispensing error is predicted to be than less 5%.
Regulatory Submissions Support system suitability and drugs regulatory submission by demonstrating consistent and reproducible glycosylation levels
Reliable Quantification Method Follows established glycan analysis techniques. Provides data comparable to gold-standard glycoprofiling methods based on monosaccharide analysis
Quick and Easy Used in QC routine in-house to determine quantity of both bulk and dispensed glycans
Use as Internal or External Quantitative Standard The Chitotriose standard can be spiked directly into your glycan sample or run in parallel.
Use as an Internal Standard Our unlabeled chitotriose standard can be used as an internal standard to quantify glycans in your sample. To do this, add a known amount of the unlabeled chitotriose to your unlabeled glycan sample. The mixture is then fluorescently labeled, cleaned up and run on HPLC/UHPLC. The unknown quantity of the glycan can be inferred by comparison of the chitotriose and glycan peak areas. The advantage of this method is that any sample loss occurring during the labelling and clean up stages will be the same for the sample and the chitotriose, thereby removing this as a source of error. The results obtained when running this method compare favourably with monosaccharide testing.
Use as External Standards The 2-AB and 2-AA labeled standard can be used as external standards to quantify glycans; these standards can be run directly on the HPLC/UHPLC. Again, the quantity of glycans in your sample is inferred by comparison of the peak areas for chitotriose (known amount) and your sample. This method is useful when quantification of already labeled glycans is required. They are also useful when quantification of several glycan samples is required in the same run, as the labeled chitotriose standard can be used as external standard for all the samples.
