| Specificity / Sensitivity | Di/Tri-Methyl-Histone H3 (Lys9) (6F12) Mouse mAb detects endogenous levels of histone H3 when di- or tri-methylated on Lys9. The antibody also shows slight cross-reactivity with histone H3 when mono-methylated on Lys9. The antibody does not cross-react with methylated histone H3 Lys4, Lys27, Lys36 or Lys79. |
| Source / Purification | Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of histone H3 in which Lys9 is tri-methylated. Western Blotting
Western blot analysis of extracts from HeLa and NIH/3T3 cell lines using Di/Tri-Methyl-Histone H3 (Lys9) (6F12) Mouse mAb. IF-IC
Confocal immunofluorescent analysis of HeLa cells using Di/Tri-Methyl-Histone H3 (Lys9) (6F12) Mouse mAb (green). Actin filaments have been labeled with DY-554 phalloidin (red). Chromatin IP
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells and either 10 μl of Di/Tri-Methyl-Histone H3 (Lys9) (6F12) Mouse mAb or 2 μl Normal Rabbit IgG #2729, using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human GAPDH Exon 1 Primers #5516, SimpleChIP® Human RPL30 Exon 3 Primers #7014, SimpleChIP® Human α Satellite Repeat Primers #4486, and SimpleChIP® Human AFM Intron 1 Primers #5098. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one. ELISA-Peptide
Di/Tri-Methyl Histone H3 (Lys9) (6F12) Mouse mAb specificity was determined by peptide ELISA. The graph depicts the binding of the antibody to pre-coated tri-methyl histone H3 (Lys9) peptide in the presence of increasing concentrations of various competitor peptides. As shown, only the di-methyl and tri-methyl histone H3 (Lys9) peptides compete away binding of the antibody. |
| Background | The nucleosome, made up of four core histone proteins (H2A, H2B, H3, and H4), is the primary building block of chromatin. Originally thought to function as a static scaffold for DNA packaging, histones have now been shown to be dynamic proteins, undergoing multiple types of post-translational modifications, including acetylation, phosphorylation, methylation, and ubiquitination (1). Histone methylation is a major determinant for the formation of active and inactive regions of the genome and is crucial for the proper programming of the genome during development (2,3). Arginine methylation of histones H3 (Arg2, 17, 26) and H4 (Arg3) promotes transcriptional activation and is mediated by a family of protein arginine methyltransferases (PRMTs), including the co-activators PRMT1 and CARM1 (PRMT4) (4). In contrast, a more diverse set of histone lysine methyltransferases has been identified, all but one of which contain a conserved catalytic SET domain originally identified in the Drosophila Su(var)3-9, Enhancer of zeste, and Trithorax proteins. Lysine methylation occurs primarily on histones H3 (Lys4, 9, 27, 36, 79) and H4 (Lys20) and has been implicated in both transcriptional activation and silencing (4). Methylation of these lysine residues coordinates the recruitment of chromatin modifying enzymes containing methyl-lysine binding modules such as chromodomains (HP1, PRC1), PHD fingers (BPTF, ING2), tudor domains (53BP1), and WD-40 domains (WDR5) (5-8). The discovery of histone demethylases such as PADI4, LSD1, JMJD1, JMJD2, and JHDM1 has shown that methylation is a reversible epigenetic marker (9).
