What is the best way to choose an antibody for my CUT&RUN assay if I cannot find a CUT&RUN validated antibody for my target protein?

When selecting an antibody for use in CUT&RUN, we recommend starting with a ChIP or ChIP-seq-validated antibody; however, we have found that not all ChIP-validated antibodies work in the CUT&RUN assay. Alternatively, Peter J. Skene et al. (2017; PMID28079019) suggest that you may want to try an antibody validated for an immunofluorescence assay, as the antibody binding in CUT&RUN takes place in an intact nuclear environment, resembling conditions for antibody binding in immunofluorescence assays.
