Patent attributes
For enhanced selection of efficient targeted genome manipulating agents, an apparatus includes first and second chip-based biosensors having one or more sensing surfaces configured to detect biomolecular binding interactions between a nucleic acid sample and a targeted genome manipulating agent functionalized to a capture surface within a sensing range of the one or more sensing surfaces. The first chip-based biosensor uses a nucleic acid sample incubated with a blocking agent that blocks on-target binding and the second chip-based biosensor holds a nucleic acid sample that omits the blocking agent. A measurement apparatus measures first and second sets of response signals produced in response to the biomolecular binding interactions occurring between the nucleic acid sample and the targeted genome manipulating agent. An analysis module determines the genome manipulating efficiency parameters of the targeted genome manipulating agent. A system and a method perform the functions of the apparatus.
