85-1342-28　Dextran Sulfate 50% Solution 100ml　CAS No:9011-18-1　D6045

特徴

• 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% liquid.
• A 50% dextran sulfate solution in water filtered through a 20um membrane and autoclaved prior to bottling in clean, sterilized bottles containing no preservatives. Liquid solution is dark brown from autoclaving.
