背景介绍 Histone methylation and demethylation is dynamically regulated by respectively histone methyl transferases and histone demethylases. Levels of H3K27 dimethylation are higher in silent genes than in active genes suggesting that this histone modification is associated with transcriptional repression. 产品介绍 Polyclonal antibody raised in rabbis against the histone H3, dimethylated at lysine 27 (H3K27me2), using a KLH-conjugated synthetic peptide.
