A Robust Protocol for Investigating the Cohesin Complex by ChIP-Sequencing

The investigation of cohesin binding sites throughout different mammalian genomes by ChIP-sequencing has been fundamental to discover how cohesin and CTCF collaborate to form chromatin loops and to gain insight in the intricate regulation of cohesin. Here we describe a detailed ChIP protocol that has been successfully used for different cohesin subunits and cohesin regulators in various cell lines.
