WebDNA binds to silica through hydrogen-binding interacation with an underivatised hydrophilic matrix provided by silica, under concentrated chaotrophic salt conditions (usually sodium iodide, sodium perchlorate, guanidinium thiocyanate) (Berensmeier, 2006). WebThus by decreasing the pH to 5 during binding, adsorption of DNA to the silica layer is possible even without the presence of chaotropic salt. Also, nucleic acids can bind with silica without the presence of chaotropic salts but under the slightly acidic condition with kosmotropic salts [6].
