| 免疫原 | This Histone H3 acetyl Lys23 antibody was raised against a peptide including acetyl-lysine 23 of histone H3. |
| 背景 | 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. |

Histone H3 acetyl Lys23 pAb tested by ChIP analysis. Chromatin IP performed using the ChIP-IT® Express Kit (Catalog No. 53008) and HeLa Chromatin (1.5 x 106 cell equivalents per ChIP) using 10 µl of Histone H3 acetyl Lys23 pAb or the equivalent amount of rabbit IgG as a negative control. Real time, quantitative PCR (RT-qPCR) was performed on DNA purified from each of the ChIP reactions using a primer pair specific for the indicated gene. Data are presented as Fold Enrichment of the ChIP antibody signal versus the negative control IgG using the ddCT method. | |

Histone H3 acetyl Lys23 pAb tested by Western blot. HeLa acid extract probed with Histone H3 acetyl Lys23 polyclonal antibody (1:5,000 dilution). Lane 1: No treatment. Lane 2: Cells treated with sodium butyrate. | |
Histone H3 acetyl Lys23 pAb tested by dot blot analysis. Dot blot analysis was used to confirm the specificity of Histone H3 acetyl Lys23 pAb for acetyl Lys23 histone H3. Acetylated peptides corresponding to the immunogen and related peptides were spotted onto PVDF and probed with the antibody at a dilution of 1:1,000. The amount of peptide (picomoles) spotted is indicated next to each row. Lane 1: Acetyl-Lys9 peptide. Lane 2: Unmodified Lys9 peptide. Lane 3: Acetyl-Lys14 peptide. Lane 4: Unmodified Lys14 peptide. Lane 5: Acetyl-Lys18 peptide. Lane 6: Unmodified Lys18 peptide. Lane 7: Acetyl-Lys23 peptide. Lane 8: Unmodified Lys23 peptide. Lane 9: Acetyl-Lys27 peptide. Lane 10: Unmodified Lys27 peptide. |
