  • Product overview

    DNMT Activity Quantification Kit (Colorimetric) ab113467 allows the user to colorimetrically measure DNA methyltransferase activity or inhibition at extremely fast speed on a 96-strip well microplate.


    The kit is ready-to-use and provides all the essential components needed to carry out a successful DNMT activity/inhibition experiment without the need for radioactivity or any special equipment.


    In the DNMT assay protocol, DNMT enzymes in a sample transfer methyl groups from Adomet to a DNMT DNA substrate coated onto microplate wells. The methylated DNA is bound with a 5-methylcytosine antibody. A secondary antibody binds the 5-methylcytosine antibody, and the enzyme-conjugated secondary antibody is detected using a chromogenic enzyme substrate.


    DNMT assay protocol summary:
    - add samples, positive controls, and samples with inhibitor to wells
    - incubate for 90-120 min, and wash wells three times with wash buffer
    - add capture antibody, incubate for 60 min, and wash wells
    - add detection antibody, incubate for 30 min, and wash wells
    - add enhancer solution, incubate for 30 min, and wash wells
    - add developer solution, incubate for 1-10 min
    - add stop solution and analyze with a microplate reader

  • Notes

    DNMT (DNA methylases) is a family of enzymes responsible for the addition of methyl groups on the cytosine ring at the 5' position of a CpG dinucleotide. The DNMT family is required for the establishment and maintenance of DNA methylation patterns.

DNMT ACTIVITY CUANTIFICATION KIT
PROTOCOL for ADIPOSE TISSUE PROTEINS
• EDM1, EDM2, EDM3 were prepared following manual instructions.
• The amount of protein obtained in the nuclear extraction of this kind of tissue was very low. Therefore, we decided to use 20 g of nuclear extract and complete with a total volume of 100 L/well. (After different probes we saw that we need this amount of protein, and we safe the proportion, 1-5 L of nuclear extract and 40-45 L of EDM3, completing with 100 L/well.)
• For blank and positive control wells, the volume was changed to 100 L/well.
• The strip-well microplate was covered with the adhesive film and was incubated in an oven at 37ºC with continued shaking during 3 hours.
• The washes were done following the instructions in all steps.
• EDM5 were prepared in a dilution rate of 1:500 and incubated in the same conditions that in the previous step (oven at 37ºC with continued shaking during 1 hour).
• EDM6 were prepared in a dilution rate of 1:1000 and incubated in the same conditions that in the previous step (oven at 37ºC with continued shaking during 30minutes).
• EDM7 were prepared in a dilution rate of 1:2000 and incubated in the same conditions that in the previous step (oven at 37ºC with continued shaking during 30minutes).
• 100 L/well of EDM8 were added and the microplate was incubating at room temperature away from direct light about 30 minutes.
• EDM9 were added to stop the enzyme reaction.
• Activity calculation was done following the instructions.

The kit is easy to use and contains all components needed to perform the colorimetric ELISA. Mouse brain samples were used with this kit. Nuclear extract was prepared (with a non abcam kit) from the previous collected mouse brain samples. From each sample 15 µg of nuclear extract was used to perform the ELISA. From here on the abcam protocol was followed. The blank an positive controls were included, and the positive control had the highest signal in my study design. Between different individual animals there was a low variation, speaking for the high sensivity and reproducibility of the kit.

Question

We have order your Episeeker DNMT activity quantification kit ab 113467 the 21th November with the number K31779. It arrived this morning. The kit is from the lot GR60607-6. I wanted to test it immediately but the vial EDM5 was completely empty also after spin down. I was really sad because i need quickly results. Do you think it's possible to send me a new complete EDM5 for permit me to test finally your kit?
Thanks

Question

Thank you for your information! That's very helpful.
As I mentioned to you, I am interested in doing some ELISA with your kit but my own coated plate. I have experience in coating plate with proteins (such as different Ig isotypes) but had never coated DNA before, is there any difference between these two procedures?

Answer

Thank you for your reply.

As far as I am aware there isn’t too much difference between coating the ELISA plates with proteins or DNA, but I did find the following publication that I think will be useful to you:

Answer

Thank you for contacting Abcam.

I have talked to the lab about the questions you had for ab113467. Please find the answers to these below:

1 - Is the microplate flat bottom or round? It is the flat bottom.

2 - What coating is used for the microplate? Wells are coated with double stranded DNA containing >25% CpGs.

3 - Length of the DNA strands used to coat the plate? The length of the DNA is >300 bps.

If there is anything else I can help you with just let me know.

Question

Abcam,
I just e-mailed a question about this kit (Cat. Ab113467), but I have another now! The Overview section talks about “a universal DNMT substrate is stably coated onto microplate wells”. I was wondering what this universal DNMT substrate is? I am assuming some sort of unmethylated DNA, but I was wondering if it’s unmethylated human genomic DNA? How long is the sequence? We are looking at a non-DNMT protein and want to determine whether it has methyltransferase activity. It may require a slightly different sequence than the DNMTs require for methylation, so I was just wondering how much variation there is in the sequence? Thanks!

Thank you for contacting Abcam and you rpatience whilst I contacted the lab about your enquiry.

The Dnmt substrate is a synthesized double stranded DNA polynucleotide ( >300 bps)containing >25%CpGs.
