有沒有人用過去DNA甲基化的酶?

超純DNA去甲基化活性/抑制分析試劑盒 貨號:A-P-3008 EpiQuik DNA Demethylase Activity/Inhibition Assay Ultra Kit (48 assays) 背景資料:DNA demethylation is necessary for the epigenentic reprogramming of genes and is also directly involved in many important disease mechanisms such as tumor progression. Demethylation of DNA can either be passive or active, or a combination of both. Passive DNA demethylation usually takes place on newly synthesized DNA strands via DNMT1 during replication rounds. Active DNA demethylation mainly occurs by the removal of 5-methylcytosine through further modified cytosine bases which have been converted by TET enzyme-mediated oxidation. These oxidation products have been shown to be repaired by TDG, a glycosylase which is involved in base excision repair, or directly converted to cytosine by DNMT3A/ DNMT3B in oxidative states. It is proposed that DNA demethylation could also be initiated by deamination of 5-mC through candidate deaminases including AID and APOBEC1, which convert 5-mC to thymine. The resulting thymine could be repaired by BER initiated by a T-G mismatch glycosylase such as MBD4 or TDG. In addition, the 5-mC base can be directly removed in plants by the DME/ROS1 family of 5-mC DNA glycosylases, resulting in an abasic site that is repaired by the BER process. 產(chǎn)品描述:The EpiQuik™ DNA Demethylase Activity/Inhibition Assay Ultra Kit is a complete set of essential components which enables an experimenter to measure total DNA demethylase activity/inhibition. The kit can be used with nuclear extracts from a broad range of species such as mammals and plants, in a variety of forms including, but not limited to, cultured cells and fresh tissues. 產(chǎn)品特點(diǎn): 1·Colorimetric assay with easy-to-follow steps for convenience and speed. The entire procedure can be completed within 4 hours; 2·Safe and innovative colorimetric assay without the need for radioactivity, extraction, or chromatography; 3·An ultra-sensitive detection limit, as low as 1 µg of nuclear extract, which is five times more sensitive than the predecessor kit; 4·96 strip-well microplate format allows for either low or high throughput analysis。 不知道您是具體想做什么實(shí)驗(yàn)?zāi)兀?img src="https://muchongimg.xmcimg.com/data/emuch_bbs_images/smilies/hand.gif" align="absmiddle" border="0"> |
