Rabbit polyclonal antibody recognizing the histone H3 monomethylated at lysine 9. Histone H3 is one of the four proteins that are present in the nucleosome, the basic repeating unit subunit of chromatin, consisting of 147 base pairs of DNA wrapped around an octamer of core histone proteins (H2A, H2B, H3 and H4). Methylation of lysine 9 is associated with transcriptional repression and the formation of heterochromatin through the recruitment of K9 methyl-binding proteins that facilitate the compaction of chromatin.
Histone H3 K9Me1 Antibody Immunogen:

Chromatin IP Data: Chromatin IP (ChIP) performed on HEK293 cell chromatin using using Histone H3 K9Me1 Antibody (black bars) or rabbit IgG (grey bars) as a negative control. Real time, quantitative PCR (RT-qPCR) was performed on DNA purified from each of the ChIP reactions using a primers specific for the gene indicated. Data are presented as ratios relative to input DNA in ChIP chromatin. (Click image to enlarge)
