how to acid washing silica beads

  • Spin column-based nucleic acid purificationWikipedia

    Procedure. The stages of the method are lyse bind wash and elute i.e. lysis of cells binding of nucleic acid to silica gel membrane washing the nucleic acid bound to the silica gel membrane and elution of the nucleic acid. To lyse the cells of a sample are processed with a lytic procedure which involves breaking the cell membrane and freeing the nucleic acid.
