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. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine.

This antibody recognizes monomethylated Lys9 at and around the N-terminal of Histone H3.

Epitope: monomethylated H3 Lys9

KLH conjugated linear peptide corresponding to monomethylated Lys9 at the N-terminal region of Histone H3.

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. 05-1248, Anti-monomethyl H3 (Lys9) at 2ug/mL (1:500) dilution. Proteins were visualized using a Donkey anti-mouse IgG conjugated to HRP and a chemiluminescence detection system.

Peptide Inhibition: Representative lot data. Specificity confirmed by the ability of immunizing peptide to abolish detection of monomethyl Histone H3 (Lys9) (Lane 7) in western blot analysis of HeLa acid extracts and various other modified histone peptides.
