How to isolate plasmid from bacteria

WebIn a typical cloning experiment, researchers first insert a piece of DNA, such as a gene, into a circular piece of DNA called a plasmid. This step uses restriction enzymes and DNA ligase and is called a ligation. After a ligation, the next step is to transfer the DNA into bacteria in a process called transformation. WebThe bacterial pellet isolated from step first is resuspended in a resuspension buffer. Resuspension buffer contains Glucose, EDTA and Tris.Cl. Glucose is required to make the solution isotonic. EDTA chelates the divalent cations which are released upon bacterial lysis. Divalent cations are required for many enzymatic reactions.
