The ChIP-FRiP pipeline quantifies co-binding and reveals how antibody background contributes to cohesin ChIP-seq patterns
The authors developed the ChIP-FRiP pipeline to systematically analyze 140 cohesin ChIP-seq datasets, revealing that antibody background and technical variability significantly distort binding patterns, and subsequently proposed a spike-in-based correction strategy integrated with biophysical simulations to enable accurate comparative analysis of cohesin positioning.
