    MethylFlash 5-mC RNA Methylation ELISA Easy Kit (Fluorometric)

    背景資料:5-methylcytosine (5-mC) in DNA occurs by the covalent addition of a methyl group at the 5-carbon of the cytosine ring by DNA methyltransferases. This process has been well studied and is generally associated with repression of gene expression. It was also observed that in humans, 5-mC occurs in various RNA molecules including tRNAs, rRNAs, mRNAs and non-coding RNAs (ncRNAs). 5-mC seems to be enriched in some classes of ncRNA, but relatively depleted in mRNAs. Levels of 5-mC are variable in animal genomes, ranging from undetectable amounts in some insects to about 0.1-0.45% of total RNA in human cells. The majority (83%) of 5-mC sites were found in mRNAs. Within these transcripts 5-mC appears to be depleted within protein coding sequences but enriched in 5’ and 3’ UTRs. Two different methyltransferases, NSUN2 and Dnmt2 are known to catalyze 5-mC modification in eukaryotic RNA. There has been strong evidence that RNA cytosine methylation affects the regulation of various biological processes such as RNA stability and mRNA translation. Furthermore, loss of 5-mC in vault RNAs causes aberrant processing into Argonaute-associated small RNA fragments that can function as microRNAs. Thus, impaired processing of vault ncRNA may contribute to the etiology of human disorders related to NSun2-defciency

    產品描述:This kit contains all reagents necessary for the quantification of global 5-mC RNA methylation. In the assay, RNA is bound to strip-wells that are specifically treated to have a high nucleic acid affinity. 5-mC in RNA is detected using capture and detection antibodies and then quantified fluorometrically by reading the fluorescence in a microplate spectrophotometer. The percentage of 5-mC RNA is proportional to the fluorescence intensity measured

    產品特點:

    Fast - The entire procedure only needs 2 hours and 40 minutes

    Robust - The kit composition allows the assay to have a large “signal window” with less variation between replicates 

    3.Convenient - Inherently low background noise, thereby eliminating the need for plate blocking steps

    4.Sensitive - Detection limit can be as low as 0.02% of 5-mC RNA from 200 ng of input RNA

    5.Specific - High specificity to 5-mC, with no cross-reactivity to unmethylated cytosine or hydroxymethylated cytosine within the indicated concentration range of the sample RNA

    6.Universal Positive and negative controls allow detection of 5-mC RNA methylation in any species

    7.Accurate - Optimized positive controls that can be fractionalized in percentage scale, allowing the assay to be more accurate and highly comparable with HPLC-MS analysis

    8.Flexible - Strip-well microplate format makes the assay available for manual or high throughput analysis

    關于5-hmC
    5-hmC是近年來在動物組織中發現的,由胞嘧啶修飾而來。5-hmC在表觀遺傳學上的功能可能與5-甲基化胞嘧啶(5-mC)不同。盡管到現在為止還不確知其功能,有研究者猜測它在調控基因的表達與關閉過程中起著重要的作用。5-mC的發現讓我們不得不重新評估DNA甲基信息,也不得不監測人類的健康組織和病理組織之間5-mC相對分布的差異。在EPI公司的MethylFlash技術之前,我們還沒有發現任何直接的常規方法來檢測5- hmC,以及區分5-hmC和5-mC

    5-hmC 和 5-mC的區別

    時下常用的DNA甲基化分析方法包括限制內切酶酶切和亞硫酸氫鹽或MeDIP介導的MS-PCR和測序,這些技術都不適合用來檢測5-hmC,因為它與5-mC事實上很難用這類方法區分開來。為了解決這個問題,EPIk研制了MethylFlash羥甲基化DNA定量試劑盒(熒光法)。本試劑盒提供了一種很經濟的方法來檢測5-羥甲基化胞嘧啶,并且區分5-hmC, 5-mC, 和 C,使得研究者能夠重新評估他們的DNA甲基化信息,也能夠在新樣品中尋找DNA羥甲基化。
