Frequently asked questions
What is dextran sulfate sodium salt commonly used for?
Dextran sulfate sodium salt is primarily used as an anticoagulant in medical and laboratory settings, as well as in research for cell culture studies, viral inhibition, and as a heparin substitute.
What is the molecular formula and molecular weight of dextran sulfate sodium salt?
The molecular weight is approximately 318.23 g/mol (repeating unit). Dextran sulfate is a polymer built from sulfated glucose units, so no single fixed molecular formula applies. The exact composition varies with chain length and degree of sulfation.
How should dextran sulfate sodium salt be stored?
Store at ambient temperature in a dry, well-ventilated area, away from moisture and direct sunlight. Keep the container tightly sealed.
What grades or purities of dextran sulfate sodium salt does Molekula supply?
Molekula supplies analytical grade and biological research grade dextran sulfate sodium salt, with varying molecular weights (e.g., 5 kDa, 500 kDa) to suit different applications.
Can Molekula supply dextran sulfate sodium salt in bulk quantities?
Yes, we offer bulk packaging options for dextran sulfate sodium salt, with quantities ranging from 1 kg to 25 kg or more, depending on availability and grade.
What documentation comes with an order of dextran sulfate sodium salt?
Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and batch-specific documentation verifying purity, molecular weight, and compliance with quality standards.
