Among other things, this paper outlines methods for mapping all DNA binding sites for a global chromatin organizing protein, SATB1. Recombinant HIS-tagged SATB1 protein is incubated with sheared genomic DNA, SATB1 with bound DNA is captured on magnetic HIS particles, and then DNA libraries are prepared from the particle-bound DNA. Illumina library construction is used, with size selection on the Pippin Prep (150-500bp).
