|Product Overview :
||Mono-Methyl Histone H3-K9 Quantification Kit (Colorimetric) is use for measuring mono-methylation of histone H3-K9.
||Epigenetic activation or inactivation of genes plays a critical role in many important human diseases, especially in cancer. A major mechanism for epigenetic inactivation of the genes is methylation of CpG islands in genome DNA caused by DNA methyltransferases. Histone methyltransferases (HMTs) control or regulate DNA methylation through chromatin-dependent transcription repression or activation. HMTs transfer 1-3 methyl groups from S-adenosyl-L-methionine to the lysine and arginine residues of histone proteins. ESET, G9a, SUV39-h1, SUV39- h2, SETDB1, Dim-5 and Eu-HMTase are histone methyltransferases that catalyze methylation of histone H3 at lysine 9 (H3-K9). In mammalian cells, mono-methyl H3-K9 is enriched in certain euchromatic domains, which have been postulated to be transcriptionally silent. The H3-K9 mono-methylation can be also changed by inhibiton or activation of HMTs. Thus quantitative detection of mono-methyl histone H3-K9 would provide useful information for better understanding epigenetic regulation of gene activation/silencing and for developing HMT-targeted drugs. The Mono-Methyl Histone H3-K9 Quantification Kit (Clorimetric) provides a tool for measuring mono-methylation of histone H3-K9.
||For specifically measuring histone H3-K9 monomethylation using a variety of mammalian cells (human, mouse, etc.) including fresh and frozen tissues, cultured adherent and suspension cells.
||For research use only (RUO)
||Upon receipt, store C3 and Standard control at –20°C. Store all other components at 4°C away from light. The components of the kit should be stable for 6 months when stored properly.Note: Check if buffers C1 and C2 contain salt precipitates before using. If so, warm (at room temperature or 37°C) and shake the buffers until the salts are redissolved.
