Dextran Sulfate (MW > 500,000) is used as an additive in probe hybridization solutions. Its presence accelerates the rate of hybridization by 10 fold. The addition of Dextran Sulfate favors the formation of probe networks, resulting in greater sensitivity during membrane-bound nucleic acid analysis. The product is supplied as a 50% (w/v) solution.
