Product Overview
The EpiQuik™ Histone Demethylase (H3-K9 Specific) Activity/Inhibition Fast Assay Kit is a convenient set of tools that allows the experimenter to measure activity/inhibition of H3-K9 specific histone demethylases using cell/ tissue extracts. The kit is ready-to-use and provides all the essential components needed for measuring histone demethylase (H3-K9 Specific) activity/inhibition from a broad range of species including mammalian cells/tissues, plants, and bacteria.
WHY CHOOSE THE EPIQUIK™ HISTONE DEMETHYLASE (H3-K9 SPECIFIC) ACTIVITY/INHIBITION FAST ASSAY KIT?
- Fast one-step assay, which can be finished within 1.5 hours.
- Innovative fluorescent assay without need for radioactivity, extraction, and chromatography.
- Measurement of HDM (H3-K9 specific) activity and inhibition through quantifying by-product of the enzyme reaction, which make the assay highly sensitive.
- Strip microplate format makes the assay flexible: manual or high throughput analysis.
- Simple, reliable, and consistent assay conditions.
组蛋白去甲基酶(H3-K9)活性/抑制快速分析试剂盒Principle & Procedure
The EpiQuik™ Histone Demethylase (H3-K9 specific) Activity/Inhibition Fast Assay Kit is designed for measuring total histone demethylase (H3-K9 Specific) activity/inhibition. In the assay with this kit, the unique methylated histone H3-K9 substrate is incubated with nuclear extracts or purified enzymes. Formaldehyde generated from the enzyme-substrate reaction reacts with a detection reagent to form a fluorescent substance. The ratio or amount of the formaldehyde, which is proportional to HDM enzyme activity, can then be fluorometrically quantified.组蛋白去甲基酶(H3-K9)活性/抑制快速分析试剂盒Product Components

文献和实验的作用是调控基因表达。例如组蛋白甲基化多导致基因沉默,去甲基化则相反;乙酰化一般是转录激活,去乙酰化则相反。当然,也可在此基础上产生复杂的生物学效应。例如组蛋白去乙酰化酶 HDAC 可影响免疫系统;H3K4me3、H3K9me2 能够调控记忆的形成, 而且 H3K 甲基化与 X 染色体失活、基因组印记和异染色质形成有关;H3 乙酰化通过多种机制调控以来 ATP 的染色质重塑 ,并参与炎症反应;H2A、H2B 泛素化则与 DNA 损害反应有关;而 H3S28 磷酸化与 H3K27 乙酰化可激活转录
家族 (KRAB-ZFPs)。这两个 标记均在失活的 X 染色体上发现,其中,H3K27me3 位于基因间和沉默的编码区,H3K9me3 主要位 于活性基因的编码区。 酶调节 组蛋白甲基化是一种可以通过多次细胞分裂而仍然保持的稳定标记,多年来一直被认为不可逆。但是, 最新研究发现,它是一个主动调控和可逆的过程。 甲基化:组蛋白甲基转移酶 (HMTs) 赖氨酸 包含 SET 结构域(组蛋白尾部) 包含非 SET 结构域(组蛋白核心) 精氨酸 PRMT(蛋白
