Histone H3 is a nuclear protein and a component of the nucleosome core, a basic unit of chromatin, that is essential for organizing genomic DNA in eukaryotic nuclei.1 It is a globular protein that contains an unstructured N-terminal tail that extends outside of the nucleosome core and is subject to various post-translational modifications (PTMs), including methylation, phosphorylation, acetylation, and citrullination.1,2 Acetylation of histone H3 at lysine 9 (H3K9Ac) is associated with active gene transcription and can recruit the super elongation complex to chromatin through direct binding with the AF9 and ENL subunits.3,4 It increases at the IFN-β promoter in HeLa cells upon infection with Sendai virus.5 Acetylation of histone H3 at lysine 9 decreases following induction of DNA damage in HeLa and U2OS cells.6 Cayman's Histone H3K9Ac Monoclonal Antibody (RM161) can be used for chromatin immunoprecipitation (ChIP), ELISA, immunocytochemistry (ICC), immunohistochemistry (IHC), multiplex-based assay, and Western blot (WB) applications.
