pK Chemicals produces Dextran Sulphate. Dextran Sulphate is a polyanionic derivative of Dextran. It is supplied as a white, sodium salt powder, stabilized by a small amount of phosphate. Dextran Sulphate is freely soluble in water and salt solutions forming a stable, clear solution, which may be sterilized by sterile filtration. The powder is stable for more than 6 years if stored at room temperature in airtight containers.

PKC manufactures Dextran Sulphates of several molecular weights ranging from mean Mw 5k to mean Mw >1000k.

The high purity and reproducible quality of Dextran Sulphate makes it suitable for many applications in molecular biology and the health-care sector. The following properties and applications are well documented:

• Accelerates hybridization rates
• Anti-coagulant properties
• Anti-viral properties
• Interaction with lipoproteins, enzymes and cells
• Cosmetic applications
• Stabilizer of proteins
