Application Notes
Applications Validated by Active Motif:
ChIP: 10 µl per ChIP
ICC/IF: 1:500 - 1:1,000 dilution
WB*: 1:1,000 - 1:5,000 dilution
For optimal results in Western blotting, primary antibody incubations should be performed overnight at 4°C. Individual optimization may be required.
*Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.

Background
Histone H3 is one of the core components of the nucleosome. The nucleosome is the smallest subunit of chromatin and consists of 147 base pairs of DNA wrapped around an octamer of core histone proteins (two each of Histone H2A, Histone H2B, Histone H3 and Histone H4). Chromatin is subject to a variety of chemical modifications, including post-translational modifications of the histone proteins and the methylation of cytosine residues in the DNA. Reported histone modifications include acetylation, methylation, phosphorylation, ubiquitylation, glycosylation, ADP-ribosylation, carbonylation and SUMOylation; these modifications play a major role in regulating gene expression.
Lysine N-ε-acetylation is a dynamic, reversible and tightly regulated protein and histone modification that plays a major role in chromatin remodeling and in the regulation of gene expression in various cellular functions. In estrogen-responsive genes, histone H3 Lys18 is acetylated by CBP/p300 following estrogen stimulation, leading to acetylation of histone H3 Lys23 and methylation of Arg17 by CARM1. These events lead to transcriptional activation of the genes.
Positive Control
Active Motif's HeLa acid extract (Sodium butyrate treated) (Catalog No. 36202) can be used as a positive control for Histone H3 acetyl Lys23 antibody.
