  • 製品の概要

    DNA methylation is a covalent modification of the cytosine ring at the 5' position, resulting in 5-methylcytosine (5-mC). In somatic cells, 5-mC is found almost exclusively in the context of paired symmetrical methylation of the dinucleotide CpG. The biological important of 5-mC as a major epigenetic modification in phenotype and gene expression has been recognized widely. Quantification of 5-mC content or global methylation status in cells such as tumor cells could provide very useful information for detection and analysis of cancer.

    Abcam's Methylated DNA Quantification Kit (Fluorometric) (ab117129) is a complete set of optimized buffers and reagents to quantify global DNA methylation by specifically measuring levels of 5-methylcytosine (5-mC) in a microplate-based format.

    It can be paired to use with Hydroxymethylated DNA Quantification Kit (Fluorometric) (ab117131), which specifically quantifies 5-hmC, for simultaneously quantification of both methylated and hydroxymethylated DNA.

  • Demonstration of high sensitivity and specificity of methylated DNA detection achieved using ab117129. Synthetic unmethylated DNA (contains 50% of cytosine) and methylated DNA (contains 50% of 5-methylcytosine) were added into the assay wells at different concentrations and then measured with ab117129.

レビューと Q&A

Having reviewed this case with the lab, I would like to offer some suggestions to help optimize the results from ab117129.

It appears that the signal may be saturated either due to

1) insufficient washing or
2) too much ti...

Thank you for contacting Abcam.

Yes, the assay detect 5-mC on both single and double stranded DNA with the nearly same sensitivity. The standard is double stranded DNA.

Please let me know if there is anything else I can...
