  • Product overview

    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.

    Methylated DNA Quantification Kit (Colorimetric) (ab117128) 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 Abcam's Hydroxymethylated DNA Quantification Kit (Colorimetric) (ab117130), which specifically quantifies 5-hmC, for simultaneous quantification of both methylated and hydroxymethylated DNA.

    • Demonstration of high sensitivity and specificity of methylated DNA detection achieved using ab117128. 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 ab117128.

    Thank you for your reply.

    Tween at 0.05 - 0.1% should be used.

    I hope this information helps.

    Thank you for your inquiry.

    I heard back from the lab that generally, PBS-T buffer may be used for washing, however for the best results, they recommend to use the wash buffer included in the kit. We could get the washing buffer (either 14 mL...
