Dextranhydrogensulphate 500 sodium salt
M ~500 000 g/mol
Dextran sulphate is a polyanion produced by esterification of dextran with chlorosulphonic acid. The standard product is based on dextran with a mean molecular weight of approx. 500.000 Dalton. Anionic dextrans such as dextran sulphate (10 % in hybridisation buffer) accelerate the hybridisation of nucleic acids by approx. 10fold.
