  • 产品概述

    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 Quantification Kit (Colorimetric) allows the user to colorimetrically measure DNA methyltransferase activity or inhibition at extremely fast speed on a 96-stripwell 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.

    • Demonstration of high sensitivity and specificity of the DNMT activity/inhibition assay achieved by using recombinant DNMT1 with ab113467.
    • Demonstration of high sensitivity and specificity of the DNMT activity assay achieved by using nuclear extracts with ab113467. Nuclear extracts were prepared from MCF-7 cells using ab113474.

    Unfortunately RNA is not a suitable sample type for this kit.

    • 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.

    DNMT activity in mouse brain

    Good Good 4/5 (Ease of Use)
    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.

    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:
