Product Description

The rabbit-derived antibody is purified with protein A-conjugated agarose followed by mono-methylated histone H3 (Lys56) peptide affinity chromatography. It specifically recognizes histone H3 with mono-methylation at Lys56.


Source/Purification

This product is produced by immunizing rabbits with a synthetic mono-methyl peptide corresponding to residues surrounding Lys56 of human histone H3. Antibodies are purified by protein A-conjugated agarose followed by mono-methylated histone H3 (Lys56) peptide affinity chromatography.


Specificity

H3

Recommended Applications

ChIP, IP. Not tested in other applications

Recommended antibody dilution

IP: 1:25 ChIP: 1:50 (2 μl of antibody for 1x 105 HeLa)

Important

 Use at an assay dependent concentration. Optimal dilutions/concentrations should be determined by the end user.

A. Dot blotting analysis on indicated amount of mono-methylated H3 peptide at Lys56 (lane 1), acetylated H3 peptide at Lys56 (lane 2), di-methylated H3 peptide at Lys56 (lane 3), tri-methylatedH3 peptide at Lys56 (lane 4) and unmodified H3 peptide at Lys56 (lane 5) using mono-methyl-histone H3 (Lys56) rabbit pAb.


B. Sonicated chromatin prepared from 1x 105 HeLa cells was subjected to chromatin immunoprecipitation (ChIP) using either serial dilutions of Mono-methyl-Histone H3 (Lys56) rabbit pAb or 1 μg of normal rabbit IgG as a negative control. Real time quantitative PCR was performed on immunoprecipitated DNA using primers specific for the human GAPDH Promoter, RPL30 Exon 3, MyoD1 Exon 1 and β-globin. Data are presented as enrichment of each IPed sample relative to total amount of input chromatin at each amplicon.


Scientific Description

The ε-amino lysine methylation of proteins is an important reversible modification controlling protein activity. The amino-terminal tails of core histones undergo lysine methylation in multiple sites, termed as “histone code” or “epigenetic code”. Lysine methylation in core histones is a major determinant for the formation of active and inactive regions of the genome and therefore plays vital roles in multiple cellular events. In most species, 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. Methylation in histones modulated by specific histone methylases (HMTs) and histone demethylases (HDMs). The level of methyllysineis found impaired in the pathologies of cancers and other diseases, therefore, enzymes regulating histone lysine methylation have become promising targets for anti-cancer drugs.


Storage & Stability
