ChIP Immunoprecipitation: Principles, Operation, and Workflow

severe

Poor Chromatin Quality from Crosslinking or Fragmentation Issues

ChIP-seq shows high background noise with poorly defined peaks. DNA fragment size distribution is inconsistent, resulting in low resolution across genomic regions.

Low Signal from Using N-ChIP for Weak DNA-Binding Proteins

Consistently low or absent signal when studying transcription factors or chromatin-associated proteins using native ChIP (N-ChIP). Histone ChIP experiments work well in the same laboratory.
