Chromatin
WebNuclear chromatin is organized into nucleosomes, with each unit consisting of 146 base pairs of DNA wrapped twice around eight core histone proteins (i.e., two copies each of H2A, H2B, H3, and H4). Nucleosomes are assembled in a long array with each nucleosome connected by 10–70 bp of linker DNA.

Chromatin Immunoprecipitation - PubMed
WebAug 3, 2024 · Chromatin immunoprecipitation, commonly referred to as ChIP, is a powerful technique for the evaluation of in vivo interactions of proteins with specific regions of genomic DNA. Formaldehyde is used in this technique to cross-link proteins to DNA in vivo, followed by the extraction of chromatin from cross-linked cells and tissues.
