How does h2o bind to silica gel

WebDNA binds to silica under high salt conditions, and releases from silica under low salt conditions. This is why binding buffers are made with salts and DNA elution buffers do not contain salt. Larger fragments are more difficult to elute because they bind more tightly to the column’s matrix.
