Description

Galactoxylan, Hydrogen Sulfate is a chemically modified polysaccharide derivative, specifically a sulfated form of galactoxylan. This modification significantly enhances its water solubility and biological activity, making it a valuable functional biopolymer for advanced applications. It is particularly sought after by research institutions and industries focused on biomaterials, pharmaceuticals, and specialty chemical synthesis.

Application

• Biomedical Research: Used as a model compound for studying sulfated polysaccharide interactions, heparin-like activity, and cell signaling pathways.
• Pharmaceutical Excipient Development: Investigated for its potential as a controlled-release matrix or stabilizer in novel drug delivery systems.
• Biomaterial Fabrication: Serves as a building block for creating hydrogels, scaffolds, and coatings with tailored surface charge and biocompatibility.
• Enzyme Substrate Studies: Acts as a specific substrate for researching the activity and kinetics of xylanases and other carbohydrate-active enzymes.
• Cosmetic Formulations: Explored for its moisturizing and film-forming properties in high-end skincare products.
• Anticoagulant Activity Screening: Utilized in preliminary research for compounds with blood-thinning properties due to its structural similarity to heparin.

Quality Control

Our Galactoxylan, Hydrogen Sulfate is produced under controlled conditions to ensure batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including assessment of degree of sulfation, polysaccharide backbone integrity, and purity. A comprehensive Certificate of Analysis (COA) detailing specific parameters is provided with every shipment to support your research and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
