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. See more The stages of the method are lyse, bind, wash, and elute. More specifically, this entails the lysis of target cells to release nucleic acids, selective binding of nucleic acid to a silica membrane, washing away particulates and … See more Even prior to the nucleic acid methods employed today, it was known that in the presence of chaotropic agents, such as sodium iodide See more • DNA separation by silica adsorption • Guanidinium thiocyanate-phenol-chloroform extraction See more WebDec 7, 2024 · Spin columns were inserted into new 1.5 ml tubes, and air dried for 10 mins. 100 μl AE buffer (Qiagen kit) or 10 mM Tris-HCl (pH8.5) was added to the filter paper in the spin column and incubated at room temperature for 5 mins.
