Product information "Dextran sulfate 500 Sodium salt"

Dextran sulfate is a polyanion produced by esterification of dextran with chlorosulphonic acid. Dextran sulfate 500 is a dextran with an average molecular weight of approx. 500,000 Daltons.

Anionic dextrans such as dextran sulfate (10% in hybridisation buffer) accelerate the hybridisation of nucleic acids by a factor of approx. 10.

Synonyms: 6-O-(6-O-beta-D-Glucopyranosyl-beta-D-glucopyranosyl)-D-glucose, Dextran 500, Manninotriose

Dextran sulfate is routinely used for

  • Selective precipitation of lipoproteins
  • Probe hybridization of membrane-immobilized DNA
  • Release of DNA from DNA-histone complexes
  • Inhibition of RNA binding to ribosomes
