A method for chromatin profiling that enables the detection of protein-DNA interactions without the need for chromatin immunoprecipitation (ChIP). The method, called CUT&RUN, involves targeting a specific protein of interest with an antibody coupled to a transposase, which then cleaves the surrounding chromatin. The resulting DNA fragments are released into solution and can be sequenced to determine the protein's binding sites. CUT&RUN offers improved specificity and sensitivity compared to traditional ChIP methods, particularly when performed on magnetic beads, and enables the analysis of low-input samples.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
Patent citations refer to prior patents cited during different phases such as opposition or international search.
