Product Description

The rabbit-derived antibody is purified with protein A-conjugated agarose followed by tri-methylated histone H3 (Lys18) peptide affinity chromatography. It specifically recognizes histone H3 with tri-methylation at Lys18.  


Source/Purification

This product is produced by immunizing rabbits with a synthetic tri-methyl peptide corresponding to residues surrounding Lys18 of human histone H3. Antibodies are purified by protein A-conjugated agarose followed by tri-methylated histone H3 (Lys18) peptide affinity chromatography.  


Specificity

H3

Recommended Applications

ELISA, WB; Not tested in other applications  

*WB=Western blotting;  


Recommended antibody dilution

WB: 1:2000

Important

For Western blotting, incubate  membrane with diluted antibody in 5% nonfat milk, 1 x TBS, 0.1% Tween-20 for  two hours at room temperature with gentle shaking.  

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

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 H3 (Lys18) 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

The antibody is delivered in powder form. After dissolved with the antibody reconstitution buffer, please store the antibody at -20°C. Avoid repeated freeze/thaw cycles. Stable for 12 months from date of receipt.
