Competition-ChIP is variant of the Chip-Sequencing

Chip-Sequencing

ChIP-Sequencing, also known as ChIP-Seq, is used to analyze protein interactions with DNA. ChIP-Seq combines chromatin immunoprecipitation with massively parallel DNA sequencing to identify the cistrome of DNA-associated proteins. It can be used to precisely map global binding sites for any...

 protocol, used to measure relative binding dynamics of a transcription factor (TF) on DNA. Since TF occupancy measures are thought to be a poor predictor of TF function at a given locus, Competition-ChIP is much more strongly linked to function than occupancy. The technique was originally developed in Jason D. Lieb's Lab in 2011.
