The Maxi Column is used for high-input workflows where sample volume and expected yield exceed the capacity of midi systems. It supports large-volume loading while maintaining stable adsorption performance.
This format is commonly used in workflows requiring milligram-scale DNA recovery from bulk biological material.
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 silica gel membrane, while other pollutants, mainly proteins, are removed by membrane washing.
