Application: [Lys(Ac)9]-Histone H3 (1–21) is a synthetic N-terminal histone H3 peptide acetylated at lysine 9, a hallmark modification of transcriptionally active chromatin. H3K9 acetylation is enriched near transcription start sites and is associated with transcription initiation, elongation, chromatin accessibility, and regulatory protein recruitment. This acetylated histone peptide is commonly used in epigenetics research to study acetyl-lysine recognition by chromatin-associated proteins, histone acetyltransferase activity, bromodomain interactions, gene expression control, and regulatory mechanisms linking histone acetylation to open chromatin states and transcriptional activation.
