The DNA-blocked “Staph-Seq” cells are ideally suited for studying recruitment of low abundance transcription factors (TF) in genome wide location analysis experiments such as ChIP-chip and ChIP-Seq. Sequencing quality modified Staph A (Staph-Seq) is achieved by employing a proprietary DNA-blocking technology to prevent Staph A DNA contamination of next-generation sequencing data in ChIP-Seq experiments. The high surface-density of endogenous protein A on the cell wall of Staph A serves as an excellent matrix to pull-down rare TF-associated chromatin complexes.Learn more about ChIP kits and protocol.
