  • Publication number: 20120322689
    Abstract: The present invention provides a method for detecting nucleic acid cleavage induced by a modified rare-cutting endonuclease derived from an initial rare-cutting endonuclease, said modified rare-cutting endonuclease being able to cleave a DNA target sequence, which may be different from the recognition and cleavage site of the initial rare-cutting endonuclease. In one embodiment of the invention expression of a marker gene is used as an indicator of target DNA cleavage.
