|Product Overview:||Histone Methyltransferase Activity/Inhibition Assay Kit (H3-K4) is use for measuring HMT activity/inhibition.|
|Description:||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. Inhibition of HMTs may lead to expression of the silenced genes, and HMT inhibitors are currently developed for various therapeutic or experimental applications. SET1, SET7/9, Ash1, ALL-1, MLL, ALR, Trx, and SMYD3 are histone methyltransferases that catalyze methylation of histone H3 at lysine 4 (H3-K4) in mammalian cells. H3-K4 methylation may serve as a epigenetic mark in euchromatin and mediates activated transcription. There is only the radioisotopic method currently available for measuring HMT activity/ inhibition, which is time consuming, labor-intensive, and has low throughput or produces radioactive waste. The Histone Methyltransferase Activity/ Inhibition Assay Kit (H3-K4) addresses these problems by using a unique procedure to measure HMT activity/ inhibition.|
|Applications:||Histone Methyltransferase Activity/Inhibition Assay Kit (H3-K4) is very suitable for specifically measuring activity/inhibition of individual histone methyltransferase targeting lysine residues at different sites.|
|Usage:||For research use only (RUO)|
|Storage:||Store HM3, HM4, HM5, HM7, and the Control Enzyme at -20°C away from light.Store all other components at 4°C away from light.The kit is stable for up to 6 months from the shipment date, when stored properly.Note: Check if wash buffer, HM1, contains salt precipitates before using. If so, warm (at room temperature or 37°C) and shake the buffer until the salts are re-dissolved.|
