RESUMEN
Genome-wide mapping of transcription factors (TFs) is critical to understand their functions. In chromatin immunoprecipitation (ChIP)-seq assay, it's challenging to study recruitment of low-abundant TFs transiently boud to the genome. Here, we present an optimized protocol using ChIP Next-Gen Seq Sepharose (Staph-seq) to efficiently pull down chromatin complexes. The double size selection promotes sensitive capture of genome-wide protein-DNA associations while eliminating potential Staph A contamination, which is a common problem in protocols using Staph A cells. For complete details on the use and execution of this protocol, please refer to Tao et al. (2020).1.
