Description

Dextran Sulfate

Dextran Sulfate is a high-purity, Sulfated Polysaccharide used in pharmaceutical, biotechnological, and biomedical applications as an antiviral agent, anticoagulant, stabilizer, and complexing agent. This anionic polymer combines excellent solubility with strong ionic charge density, enabling diverse uses in drug formulation and biologics manufacturing. Dextran Sulfate

• Is a high-purity Sulfated Polysaccharide derived from Dextran
• Is used as an antiviral and anticoagulant agent in pharmaceutical development
• Functions as a stabilizer, viscosity modifier, and polyanionic excipient
• Is suitable for injectable formulations, controlled-release matrices, and cell culture applications
• Is manufactured under Good Manufacturing Practice (GMP) certified conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and supporting technical data

Dextran Sulfate is produced by the controlled Sulfuric Acid esterification of Dextran, resulting in a highly water-soluble powder with strong polyanionic properties. The molecular weight and degree of sulfation can be tailored to meet specific application requirements.

In pharmaceutical and biotechnology applications, Dextran Sulfate is used in:

• Injectable formulations for antiviral therapies and anticoagulant preparations
• Stabilization of proteins and biologics by preventing aggregation and adsorption
• Complexation of cationic compounds and peptides for controlled-release systems
• Cell culture media as a growth factor carrier and polyanionic supplement
• Research applications studying viral inhibition, coagulation, and immune modulation

Dextran Sulfate demonstrates dose-dependent anticoagulant and antiviral effects by interacting with coagulation factors and viral envelope proteins, making it a valuable tool in development and research settings.

CarboMer supplies Dextran Sulfate with rigorous controls over molecular weight distribution, degree of sulfation, residual solvents, and microbial content. Each lot is fully traceable and produced under GMP conditions to support regulated use.

The material is packaged in sealed, moisture-protected, tamper-evident containers. Available in research, pilot, and commercial-scale quantities. Minimum order quantities (MOQ), lead times, and complete technical documentation are available upon request.

Each batch is tested for identity, sulfur content, molecular weight profile, heavy metals, endotoxins, and microbial purity. Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full supporting data are included with every shipment.

As with all CarboMer specialty excipients and biopolymers, Dextran Sulfate is supported by technical formulation guidance, regulatory assistance, and secure supply chain logistics to help you bring innovative therapies and biologics to market.
