Histone H2BK46ac antibody (pAb) tested by ChIP.

Histone H2B acetyl Lys46 pAb tested by ChIP.
Chromatin IP performed using the ChIP-IT® Express Kit (Catalog No. 53008) and 50 µl of Ready-to-ChIP HeLa Chromatin (Catalog No. 53015) per ChIP. Subsequent to the ChIP reaction, DNA was purified from the immunoprecipitated chromatin and a region of the human GAPDH promoter was amplified by PCR.
    Lane 1: ChIP using negative control rabbit IgG.
    Lane 2: ChIP using 10 µl of Histone H2B acetyl Lys46 pAb.
    Lane 3: PCR input control.

Histone H2BK46ac antibody (pAb) tested by dot blot analysis.

Histone H2B acetyl Lys46 pAb tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of Histone H2B acetyl Lys46 pAb for acetyl Lys46 histone H2B. Decreasing amounts of acetylated peptides corresponding to the immunogen and related sequences were spotted onto PVDF and probed with the antibody at 1:4,000.
    Lane 1: acetyl Lys46 histone H2B peptide.
    Lane 2: unmodified Lys46 histone H2B peptide.
No detection of peptides (acetylated) corresponding to lysine 9, 14, 18, 23, 27, and 56 of Histone H3 was observed with Histone H2B acetyl Lys46 pAb.
In addition, no detection of peptides (acetylated) corresponding to lysine 5, 15, 16, and 120 of Histone H2B was observed with Histone H2B acetyl Lys46 pAb.

for Histone H2B acetyl Lys46 antibody (pAb)Background

Histone H2B 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. Histone H2A and Histone H2B are acetylated in bulk chromatin by p300 and form acetylated Histone H2A/Histone H2B heterodimers. When DNA associates with intact core histone octamers that contain acetylated H2A/H2B dimers, the inhibition of transcriptional initiation significantly decreases, indicating that acetylation of their lysine residues may mediate transcription.
