ChargeSwitch® technology (CST) is the simplest, cleanest, and most effective modern technology for the purification of all types of nucleic acids. Unlike all popular DNA/RNA purification methods, CST ® technology does not utilize hazardous or caustic chemicals, which are known to compromise the efficiency of many downstream processes such as PCR and other enzymatic applications. ChargeSwitch® technology is the first significant breakthrough in DNA and RNA extraction purification techniques in more than 20 years providing fast, inhibitor-free purification without a centrifuge, vacuum, chaotropic salts, solvents, or ethanol!
