Affinity Chromatography Media
For use in the concentration, purification and depyrogenation of virus, viral/microbial antigens and heparin-binding proteins.
Advances in vaccines and clinical diagnostics have created an increasing demand for large volumes of highly purified and concentrated virus and viral or microbial antigens. Cellufine Sulfate affinity media is based on spherical cellulose beads functionalized with a low concentration of sulfate esters, and is a simple, rapid and effective means for the concentration, purification and depyrogenation or viral and microbial antigens and specific proteins.
- Affinity for a wide range of live, killed or disrupted viruses, viral or microbial antigens and heparin-binding proteins.
- Closed column operation assures safety and product sterility
- Endotoxins do not bind, allowing a rapid and contaminant free depyrogenation
- Rigid, high-strength beads.
- More effective than ultracentrifugation at removing contaminants from culture media and host cells
- Avoids excessive product handling and safety concerns, particularly with viral preparations
- Simultaneous concentration and purification improve yield, reduce processing steps, time and costs
- Gentle binding and elution conditions provide high capacity and product yield
- Resists compression, providing rapid flow for high-speed processing, even in large columns, making it easily scalable
- Resistant to chemical depyrogenation with base and chemically sterilizable with formalin
- Can reduce or eliminate the expense, ligand leakage and reproducibility problems associated with immobilized dextran sulfate, chondroitin sulfate or heparin

Concentration and Purification of Virus with Cellufine Sulfate
Purification of Influenza Virus
Hen’s egg allantoic fluid was loaded directly onto a 33.3 mL gel bed and 94.5% virus was recovered in the eluate fraction

Purification of Influenza virus from hen’s egg allantoic fluid. Column: 50 x 170mm, Buffer: 0.01M Phosphate (pH 7.4), Wash: 0.01M Phosphate (pH 7.2) + 0.2M NaCl, Elution: 0.01M Phosphate (pH 7.0 + 1.5M NaCl
Cellufine Sulfate mimics the affinity of heparin or dextran sulfate for many proteins. It can function as an affinity support for selected plasma proteins, cellular growth factors and lipases, and its capacity is comparable to conventional heparin gels.
