Below you will find the answers to the most frequently asked questions.
Product usage information
Dextran Sulfate Sodium (DSS)
The dose range lies between 2-3.5% DSS. If you have not run any studies before, we recommend testing a few animals at 2%, 2.5% and 3% DSS.
There are three important parameters when performing experiments with DSS:
- Dosage The dose range lies between 2-3.5% DSS. If you have not run any studies before, we recommend testing a few animals at 2%, 2.5% and 3% DSS.
- The animals being studied. You must obtain a certificate from the supplier defining the following:
- Conditions during treatment
- Amount of DSS-treated water that the animals drink
- Exercise levels
- Light levels
- Other room conditions
High molecular weight dextran
All high molecular dextran derivatives (≥150 kDa), with or without an attached dye, will be soluble when heated to 50 °C during continuous stirring for 30 min.
FITC Inulin and blue dextran
FITC inulin, and in some cases also blue dextrans, will be soluble when heated to 80 °C during continuous stirring.
DEAE- and CM-dextran
DEAE- and CM-dextrans will be dissolved faster if you add the powder to water (not the other way around) during continuous stirring.
Dextran with a high polar aromatic substance
Dextran derivatives with a molecular weight ≥1000 kDa with a high polar aromatic substance are recommended to be heated to 50 °C during continuous stirring. Even if the substance looks dissolved; it can form an invisible globular structure in solution.
The shipping condition for all our products is room temperature.
