Anti-Histone H3

Anti-Histone H3 is directed against the human histone 3 protein. The product was protein A purified from monospecific antiserum by immunoaffinity chromatography using protein A coupled to agarose beads. A BLAST analysis was used to suggest reactivity with human and multiple other eukaryotic. Cross-reactivity with histone-3 from other sources have not been determined. Protein function: Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. [The UniProt Consortium]
