Product Overview	m6A Demethylase Assay Kitis a complete set of optimized buffers and reagents to colorimetrically measure the activity/inhibition of total m6A demethylases using nuclear extracts or purified m6A demethylases like FTO and ALKBH5. m6A demethylase activity may be measured in a broad range of species such as mammalian, plant, fungal, and bacterial, in a variety of forms including, but not limited to, cultured cells and, fresh and frozen tissues. A unique m6A substrate is stably coated on the strip wells. Active m6A demethylases bind to and demethylate m 6A contained in the substrate. The un-demethylated m6A in the substrate can be recognized with a high affinity m6A antibody and the immuno-signal is enhanced with enhancer solution. The ratio or amount of undemethylated m6A, which is inversely proportional to enzyme activity, can then be colorimetrically quantified through an ELISA-like reaction.
Notes	N6-methyladenosine (m6A) is the most common and abundant modification on RNA molecules present in eukaryotes. Recently, DNA m6A was also identified in multicellular eukaryotes including Caenorhabditis elegans and Drosophila melanogaster, and furthermore identified in higher eukaryotes including plants, mouse and human cells. m6A plays crucial roles in regulating DNA replication, DNA damage, RNA splicing, transposition, transcription and cellular defense. In human cells, the m6A modification is catalyzed by a methyltransferase complex METTL3/METTL14 and removed by the α-ketoglutarate (α-KG) and Fe2+-dependent dioxygenases such as FTO, ALKBH5 and TET-like enzymes. The dynamic and reversible chemical m6A modification on DNA/RNA may also serve as a novel epigenetic marker of profound biological significance. m6A is found to be the most regulated DNA modification in cancers. Thus, determination of such enzymes would be important in benefiting cancer diagnostics and developing new target-based cancer therapeutics.
