for Histone H2B acetyl Lys16 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. The acetylation of Histone H2B at Lys16 is associated with transcriptional activation and is involved in cell survival process.
for Histone H2B acetyl Lys16 antibody (pAb)Immunogen
This antibody was raised against a peptide including acetyl-lysine 16 of human histone H2B.
for Histone H2B acetyl Lys16 antibody (pAb)Application Notes
This Histone H2B acetyl Lys16 antibody (H2BK16Ac) has been validated for use in chromatin IP (5 - 10 µl per ChIP) and in Western blotting (1:5,000 - 1:20,000 dilution). Specificity for H2B acetylated at lysine 16 has been confirmed by dot blot. This Histone H2B acetyl Lys16 antibody is specific for histone H2B acetylated at lysine 16. Due to evolutionary conservation, a wide range of species reactivity is expected. At higher concentrations of antibody (1:1,000), a cross-reacting band of 23 kDa is observed.
