Product Name:  Di-Methyl Histone H4K20 Quantification Kit (Fluorometric)
Product Overview:  Di-Methyl Histone H4K20 Quantification Kit (Fluorometric) is used for measuring di-methylation of histone H4K20.
Description:  Epigenetic activation or inactivation of genes play 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 transcriptional repression or activation. HMTs transfer 1-3 methyl groups from S-adenosyl-L-methionine to the lysine and arginine residues of histone proteins. PR-SET7, SET9, SUV4.20h, and ASH1are histone methyltransferases that catalyze methylation of histone H4 at lysine 20 (H4K20) in mammalian cells. Di-methylation of H4K20 has been de-scribed as another repressive chromatin domain and is involved in DNA damage response. The H4K20 di-methylation can also be changed by inhibiton or activation of HMTs, making quantitative detection of di-methyl histone H4K20 a useful tool for better understanding epigenetic regulation of gene activation/repression. This information is also useful for developing HMT-targeted drugs. Di-Methyl Histone H4K20 Quantification Kit (Colorimetric) provides a tool for measuring di-methylation of histone H4K20.
Applications:  Di-Methyl Histone H4K20 Quantification Kit (Fluorometric) is suitable for specifically measuring histone H4K20 di-methylation using a variety of mammalian cells (human, mouse, etc.) including fresh and frozen tissues, cultured adherent and suspension cells.

Features & Benefits:  Quick and efficient procedure, which can be finished within 2.5 hours.Innovative fluorometric assay witout the need for radioactivity, electrophoresis, or chromatography.Specifically captures di-methylated H4K20 with the detection limit as low as 1 ng/well and detection range from 10 ng-2 µg/well of histone extracts.The control is conveniently included for quantification of di-methylated H4K20.Strip microplate format makes the assay flexible: manual or high throughput.Simple, reliable, and consistent assay conditions.
Detection Method:  Fluorometric
Sample Types:  Histone Extract
Storage:  Upon receipt, store F4 and standard control at –20°C. Store all other components at 4°C away from light. The components of the kit are stable for up to 6 months from date of shipment when stored properly.Note: Check if buffers F1 and F2 contain salt precipitates before using. If so, warm (at room temperature or 37°C) and shake the buffers until the salts are re-dissolved.
