Product Overview :
Pan-Methyl Histone H3-K9 Quantification Kit (Colorimetric) is use for measuring mono-, di-and tri-methylation of histone H3-K9.
Description :
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 are enriched in certain euchromatic domains, which have been postulated to be transcriptionally silent. H3-K9 di- and tri-methylation mediates heterochromatin formation by forming a binding site for HP1 and also participates in silencing gene expression at euchromatic sites. Increased H3-K9 methylation is also found to be involved in some pathological processes such as cancer progression. The patterns of H3-K9 methylation can be also changed by inhibiton or activation of HMTs. Thus quantitative detection of the patterns of histone H3-K9 methylation would provide useful information for better understanding epigenetic regulation of gene activation/silencing and for developing HMT-targeted drugs. The Pan-Methyl Histone H3-K9 Quantification Kit (Colorimetric) provides a tool for measuring mono-, di- and tri-methylation of histone H3-K9.
Applications :
For simultaneously measuring histone H3-K9 mono-, di-, and tri-methylation using a variety of mammalian cells (human, mouse, etc.) including fresh and frozen tissues, cultured adherent and suspension cells.
Usage :
For research use only (RUO)
Storage :
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.
