Polyanionic Polysaccharide for Colitis Research & Biomedical Applications
Thermo Fisher Scientific™ Dextran Sulfate Sodium (DSS) is a high-purity polyanionic derivative of dextran, produced by esterification of dextran with chlorosulfonic acid. DSS is widely used in biomedical and clinical research, particularly in inflammatory bowel disease (IBD) models and antiviral studies.
As a high molecular weight (≥500,000 Da) sodium salt, DSS is freely soluble in water and salt solutions, forming a stable, clear solution with controlled sulfation levels (17–20% sulfur content). This product is highly effective in inducing experimental colitis in animal models, making it an essential reagent for colitis research and IBD therapeutics evaluation.
Key Features & Benefits
✅ High Molecular Weight (≥500,000 Da) – Ensures reproducibility in biomedical applications
✅ Controlled Sulfation (17–20%) – Consistent biological activity with 1.9 sulfate groups per glucosyl residue
✅ Water-Soluble & Stable – Freely dissolves in aqueous solutions for easy preparation
✅ Proven Model for IBD Research – Induces chronic colitis in animal studies
✅ Versatile Biomedical Applications – Used in colitis studies, antiviral research, and macromolecular drug delivery
Applications
🔬 Inflammatory Bowel Disease (IBD) Research – Used to induce colitis in animal models (mice & rats)
🦠 Colitis-Associated Cancer Studies – Evaluates therapeutic interventions for IBD-related cancers
🧬 Antiviral Research – Studied as a potential antiviral agent
🛠️ Biopolymer & Drug Delivery Systems – Used in drug formulation & macromolecular studies
