Insertional chromatin immunoprecipitation: A method for isolating specific genomic regions

We established a novel method, insertional chromatin immunoprecipitation (iChIP), for isolation of specific genomic regions. In iChIP, specific genomic domains are immunoprecipitated with antibody against a tag, which is fused to the DNA-binding domain of an exogenous DNA-binding protein, whose recognition sequence is inserted into the genomic domains of interest. The iChIP method will be a useful tool for dissecting chromatin structure of genomic region of interest.
