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 H2BK46me2 antibody (pAb) tested by dot blot analysis.

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.


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. The methylation of histones can occur on two different residues: arginine or lysine. Changes in methylation of histone H2B seem to be involved in heat-shock mechanisms.

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
