Description

General description

Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the ′beads on a string′ structure. Histone proteins are highly post-translationally modified, and Histone H3 is the most extensively modified of the five histones. Histone H3 sequence variants and variable modification states are thought to play a role in the dynamic and long term regulation of genes. Di- and tri-methylation of histone H3 are gene silencing marks, while removal of these marks by the demethylase genes Jmjd1a and Jmjd2c leads to gene activation.

Specificity

Broad species cross-reactivity is expected, based on sequence homology.

This antibody recognizes Histone H3 dimethylated at Lys9. Phosphorylation of Ser10 interferes with antibody binding to dimethyl Lys9.

Immunogen

Epitope: dimethyl Lys9

Synthetic peptide corresponding to amino acids 1-19 of human Histone H3, dimethylated on Lys9, conjugated to KLH.

Application

Chromatin Immunoprecipitation::
Sonicated chromatin prepared from HeLa cells (1 X 106 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either a normal mouse IgG, or Anti-dimethyl Histone H3 (Lys9) antibody, clone CMA307 and the Magna ChIP G (Cat. # 17-611) Kit. Successful immunoprecipitation of dimethyl-histone H3 (Lys9) associated DNA fragments was verified by qPCR using ChIP Primers B-Globin.
Please refer to the EZ-Magna G ChIP (Cat. # 17-409) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.

Dot Blot Analysis: Absurance Histone H3 Antibody Specificity Array (Cat. No. 16-667) and Absurance Histone H2A, H2B, H4 Antibody Specificity Array (Cat. No. 16-665), which contain histone peptides with various modifications were probed with Cat. No 05-1249-S, Anti-dimethyl H3 (Lys9), clone CMA307 at 2.0ug/mL (1:500) dilution. Proteins were visualized using a Donkey anti-mouse IgG conjugated to HRP and a chemiluminescence detection system.

ELISA:
This antibody has been shown by an outside laboratory to be suitable for ELISA. Kimura, H., et al. (2008). Cell Struct. Funct. 33: 61-73.
