Geração de alta Chromatin Template DNA Immunoprecipitation Qualidade para seqüenciamento de alto rendimento (CHIP-seq)

Overview

This article outlines a procedure for identifying protein binding regions using chromatin immunoprecipitation (ChIP). The method involves cross-linking proteins to DNA, shearing the DNA, immunoprecipitating the protein-DNA complex, and isolating the DNA for sequencing.
