WebSpin column-based nucleic acid purification. Silica in a spin column with water and with DNA sample in chaotropic buffer. Spin column-based nucleic acid purification is a solid phase extraction method to quickly purify nucleic acids. This method relies on the fact that nucleic acid will bind to the solid phase of silica under certain conditions.
