Histone H3 monomethyl Lys23 pAb tested by Western blot.
HeLa cell nuclear extract (20 µg per lane) was probed with Histone H3 monomethyl Lys23 pAb at a dilution of 1:1,000.

Histone H3 monomethyl Lys23 pAb tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of Histone H3 monomethyl Lys23 pAb for monomethyl Lys23 histone H3. Methylated peptides corresponding to the immunogen and related sequences derived from histone H3 were spotted onto PVDF and probed with the antibody at 1:5,000. The amount of peptide (picomoles) spotted is indicated next to each row.

Lane 7: Dimethyl lysine 23. Lane 8: Trimethyl lysine 23. Lane 9: Unmod H3 aa 22-32 peptide. Lane 10: Monomethyl lysine 27. Lane 11: Dimethyl lysine 27. Lane 12: Trimethyl lysine 27.

Background

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.

The methylation of histones can occur on two different residues: arginine or lysine. Histone methylation can be associated with transcriptional activation or repression, depending on the methylated residue.

Positive Control

Active Motif's HeLa acid extract (Catalog No. 36200) can be used as a positive control for Histone H3 monomethyl Lys23 antibody.
