Histone H2B dimethyl Lys46 pAb tested by Western blot.
HeLa acid extract (10 µg per lane) probed with Histone H2B dimethyl Lys46 pAb (1:2,000 dilution).

Histone H2B dimethyl Lys46 pAb tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of Histone H2B dimethyl Lys46 pAb for dimethyl Lys46 histone H2B. Methylated peptides corresponding to the immunogen and related sequences derived were spotted onto PVDF and probed with the antibody at 1:20,000. The amount of peptide (picomoles) spotted is indicated next to each row.
    Lane 1: unmodified histone H2B peptide.
    Lane 2: monomethyl Lys46 H2B peptide.
    Lane 3: dimethyl Lys46 H2B peptide.
    Lane 4: trimethyl Lys46 H2B peptide.
    Lane 5: dimethyl Lys4 H3 peptide.

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). Histone H1 is a linker histone, present at the interface between the nucleosome core and DNA entry/exit points; it is responsible for establishing higher-order chromatin structure. 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; they play a major role in regulating gene expression. The methylation of histones can occur on two different residues: arginine or lysine. Changes in methylation of histone H2B may be involved in heat-shock mechanisms.

Positive Control

Active Motif's HeLa acid extract (Catalog No. 36200) can be used as a positive control for Histone H2B dimethyl Lys46 antibody.
