Histone Demethylase (H3-K4 Specific) Activity/Inhibition Assay Kit

Cat.No.: Kit-0445
Product Overview: Histone Demethylase (H3-K4 Specific) Activity/Inhibition Assay Kit is use for measuring activity/inhibition of H3-K4 specific histone demethylases using cell/tissue extracts.
Description: Lysine histone methylation is one of the most robust epigenetic marks and is essential for the regulation of multiple cellular processes. The methylation of H3- K4 seems to be of particular significance, as it is associated with active regions of the genome. H3-K4 methylation was considered irreversible until the identification of a large number of histone demethylases indicated that demethylation events play an important role in histone modification dynamics. So far at least 2 classes of H3-K4 specific histone demethylase, LSD1 and JARIDs have been identified. LSD1 can remove di- and mono-methylation from H3-K4 by using an amine oxidase reaction, while JARIDs such as RBP2, PLU-1, SMCX, and SMCY catalyzes the removal of methylation by using a hydroxylation reaction and required iron and α-ketoglutarate as cofactors. H3-K4 specific demethylases are found to be involved in some pathological processes such as cancer progression. Inhibition of the enzymes may lead to re-methylation of H3-K4 and silencing of H3-K4 enriched active genes, there is few methods currently available for measuring activity/inhibition of H3-K4 specific methylases using a variety of cells/tissues. The Histone Demethylase (H3-K4 Specific) Activity/Inhibition Assay Kit uses a proprietary and unique procedure to measure activity/inhibition of H3-K4 specific histone demethylases using cell/ tissue extracts.
Applications: The Histone Demethylase (H3-K4 Specific) Activity/Inhibition Assay Kit is very suitable for measuring Histone Demethylase (H3-K4 Specific) Activity/Inhibition from a broad range of species including mammalian cells/tissues, plants, and bacteria.
Usage: For research use only (RUO)
Storage: Upon receipt: (1) Store HD3, HD4, HD6 and HD7 at –20°C away from light; (2) 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, HD1, contains salt precipitates before using. If so, warm (at room temperature or 37°C) and shake the buffer until the salts are re-dissolved.
