WebWhat is ChIP-seq? ChIP-seq is short for chromatin immunoprecipitation-sequencing. Fundamentally, ChIP-seq is the sequencing of the genomic DNA fragments that co-precipitate with a DNA-binding protein that is under study. The DNA-binding proteins most frequently investigated in this way are transcription factors (for example, p53 or NFκB), ... WebIf it is not known in the literature whether a mark is peaky or broad, evidence might come from FISH studies or Low throughput qPCR. Another way to look would be to examine the signal expressed as fold enrichment over input on a genome browser and look if peaks tended to be small (a few hundred bp, e.g. a transcription factor), or large ...
