Description

Xyloglucan Octasaccharide CAS NO 121591-99-9 is a well-defined, oligomeric carbohydrate derived from the enzymatic or chemical hydrolysis of xyloglucan, a major hemicellulose in plant cell walls. This specific octasaccharide is a crucial tool compound for fundamental research in plant biology and carbohydrate chemistry, enabling the study of cell wall architecture, enzyme specificity, and signaling pathways. It is primarily utilized by researchers in academic institutions, biotechnology firms, and agricultural science laboratories for advanced biochemical studies and as a standard for analytical method development.

Application

• Biochemical Research Standard: Used as a high-purity reference standard in chromatography (HPLC, HPAEC-PAD) and mass spectrometry for the identification and quantification of xyloglucan-derived oligosaccharides.
• Enzyme Substrate & Inhibitor Studies: Serves as a specific substrate for characterizing the activity and kinetics of xyloglucan-specific enzymes like endo-glucanases, xyloglucan endotransglycosylases (XETs), and glycosidases.
• Plant Cell Wall & Growth Research: Employed to investigate the role of xyloglucan oligosaccharides in cell wall loosening, expansion, and the structural dynamics of the cellulose-xyloglucan network.
• Carbohydrate Synthesis & Conjugation: Acts as a defined building block or precursor for the chemical or enzymatic synthesis of more complex glycoconjugates, neoglycoproteins, or labeled probes.
• Signal Molecule Studies: Utilized in plant physiology research to study the potential role of specific oligosaccharides as signaling molecules affecting growth, development, and stress responses.
• Material Science & Biomaterials: Investigated for its potential in creating bio-based, functional materials such as hydrogels, films, or drug delivery vehicles due to its biocompatibility and specific molecular interactions.

Quality Control

Our Xyloglucan Octasaccharide is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity, suitable for sensitive research applications. Each lot is characterized using advanced analytical techniques including High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection (HPAEC-PAD) and/or Mass Spectrometry (MS) to confirm structural identity and oligomeric purity. A comprehensive Certificate of Analysis (COA) detailing purity, identification, and moisture content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture absorption.
