Immunogen
This Histone H3 [ac Lys9] antibody (AH3-120) was raised against a synthetic, acetylated histone H3 peptide (amino acids 7-20, acetyl K9) corresponding to the N-terminus of human histone H3, conjugated to KLH.
Reactivity Notes
Cross-reacts with Human. Expected to cross-react with Mouse, Rat, Xenopus laevis, Cow, a wide range of other species, C. elegans, Chicken and Drosophilia melanogaster due to very high or perfect sequence identity across many species. Not yet tested in other species. Please note that this antibody is reactive to Mouse and derived from the same host, Mouse. Additional Mouse on Mouse blocking steps may be required for IHC and ICC experiments. Please contact Technical Support for more information.

Application Notes
WB: Detects a band of approximately 17 kDa (determined using a whole cell extract of mouse fibroblasts 3T3 cell line treated with sodium butyrate). We advise you to centrifuge this product vial before use. ELISA: indirect. Staining of (acetyl K9) histone H3 in WB is specifically inhibited with the immunizing peptide. There is no inhibition with non-acetylated histone H3 peptide.

Background: Histone H3
Histones are nuclear proteins responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Changes in chromatin structure play a large role in the regulation of transcription. The chromatin fibers are compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures.
Common histone modifications include methylation of lysine and arginine, acetylation of lysine, phosphorylation of threonine and serine, and sumoylation, biotinylation, and ubiquitylation of lysine. Posttranslational modifications such as acetylation of core histones regulates gene expression, thus altering protein function and regulation (1). Histone H3 is primarily acetylated at lysines 9, 14, 18, and 23 and have a theoretical molecular weight of 15 kDa. Acetylation at lysine 9 and 14 appears to control histone deposition, chromatin assembly and active transcription. Methylation of arginine residues within histone H3 has also been linked to transcription regulation. Histone H3 has been linked to various types of cancer as a biomarker through the aberrant expression of histone deacetylase (HDAC) enzymes and changes to chromatins (2-4).
