Product Description

The rabbit-derived antibody is purified with protein A-conjugated agarose followed by di-methylated histone H3 (Lys36) peptide affinity chromatography. It specifically recognizes histone H3 with di-methylation at Lys36.   

Source/Purification

This product is produced by immunizing rabbits with a synthetic di-methyl peptide corresponding to residues surrounding Lys36 of human histone H3. Antibodies are purified by protein A-conjugated agarose followed by di-methylated histone H3 (Lys36) peptide affinity chromatography.

Scientific Description

The ε-amino lysine acetylation 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) is impaired in the pathologies of cancer and other diseases and therefore, enzymes regulating histone lysine methylation have become promising targets for anti-cancer drugs.
