Although the adsorption mechanism remains the same as DNA columns, this format is used in RNA-focused workflows where consistency and recovery of total RNA are required.
It is commonly used in RNA cleanup steps or integrated into RNA extraction systems where the column structure needs to handle aqueous RNA conditions without compromising binding stability.
Based on the negatively charged DNA skeleton, it has a high affinity for positively charged glass fibers. In high salt and ethanol solutions, DNA/RNA binds to glass fiber and interacts with hydrophilic matrix on silica through hydrogen bond. DNA/RNA is tightly bound. All pollutants can be removed by washing solution. At high salt concentration, nucleic acids selectively bind to silicagel membrane, while other pollutants, mainly proteins, are removed by membrane washing.
