ChIRP, also commonly referred to as ChIRP-seq, is a protocol to detect the locations on the genome where ncRNAs, such as lncRNAs, and their proteins are bound. In this method, samples are first crosslinked and sonicated. Biotinylated tiling oligos are hybridized to the RNAs of interest, and the complexes are captured with streptavidin magnetic beads. After treatment with RNase H, the DNA is extracted and sequenced. Deep sequencing can determine the lncRNA/protein interaction site at single-base resolution.
