Chip-seq

Definition

ChIP-seq, or Chromatin Immunoprecipitation Sequencing, is a powerful method used to analyze protein-DNA interactions in the genome. By using specific antibodies to pull down proteins bound to DNA, researchers can identify the locations of these interactions and gain insights into gene regulation and epigenetic modifications.
