    • 常规说明

      DNMT 3L is a nuclear protein which has similarity to DNA methyltransferases, involved in de novo methylation of CpG islands. CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a nuclear protein with similarity to DNA methyltransferases. This protein is not thought to function as a DNA methyltransferase as it does not contain the amino acid residues necessary for methyltransferase activity. However, this protein does stimulate de novo methylation by DNA cytosine methyltransferase 3 alpha and it is thought to be required for the establishment of maternal genomic imprints. This protein also mediates transcriptional repression through interaction with histone deacetylase 1.

      The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing this with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    靶标

    • 功能

      Catalytically inactive regulatory factor of DNA methyltransferases. It is essential for the function of DNMT3A and DNMT3B. Activates DNMT3A and DNMT3B by binding to their catalytic domain. Accelerates the binding of DNA and AdoMet to the methyltransferases and dissociates from the complex after DNA binding to the methyltransferases. Recognizes unmethylated histone H3 lysine 4 (H3K4) and induces de novo DNA methylation by recruitment or activation of DNMT3.

    • 组织特异性

      Expressed at low levels in several tissues including testis, ovary, and thymus.

    • 序列相似性

      Belongs to the C5-methyltransferase family.
      Contains 1 ADD-type zinc finger.

      Question

      Hi,

      I have a question about the epigenetics antibody https://www.abcam.com/Dnmt3L-antibody-ab3493.html&tab=abreviews, anti-DNMT3L.

      I would like to test DNMT3L levels in mouse by western blot –has this antibody been tested for cross-reactivity to DNMT3A and 3B? I couldn’t find any information about this on your website.

      Many thanks,

      Read More
      Answer

      Thank you for your inquiry.
      I can confirm that it was not experimentally tested if this antibody shows any cross-reaction with the proteins DNMT3A and/or DNMT3B.
      After performing a short BLAST search with the antigen, it is very unlikely that the antibody cross-reacts.
      The BLAST search did not bring up these proteins in any species, but only showed DNMT3L proteins from different species.
      I hope this information is helpful and wish you good luck with your research.

      Question

      Thanks for your kindly reply, this customer reply your question as follow:


      Reply to 1:
      Although the datasheet showed that it did not work in a straight WB. But the datasheet provided a direct Western data as well.


      Reply to 2.1
      The Dnmt3L expression vector.

      YES, the vector contains full sequence of the target protein. The sequence has been check by DNA sequencing.


      Reply to 2.2
      No tag in the vector.

      Reply to 2.3
      We got the Dnmt3L -/- ES cell line that was KO by gene targeting disruption.We did not use siRNA to knockdown the target protein. So we did not have to checking the siRNA sequence.

      Reply to 2.4
      The KO line was well used and published previously and it has been checked by southern blot. We used the same KO line that was published in 2002 (please check the attached file figure 2). We got the KO line from the first author’s lab.

      I also attached the results in this letter; the image shows he used the other primary antibody from other company to check the sample and it seems get a great result, could you please check it and help this customer to solve the problem.

      Thanks for your kindly help

      Answer

      Thank you for your enquiry regardingab3493 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that your customer ishaving problems with this antibody.

      After reading through the detailed protocol you kindly forwarded to Abcam, I would like to make the following comments/suggestions:

      1) Immunoprecipitation: As the datasheet indicates, ab3493 worked in WB following IP, but did not work in a straight WB. Please advise your customer to perform an IP firts.

      2) Transfection and KO: As teh customer has used transfected cells lines and KO cells, it would be great if you could provide some more details:

      2.1 Does the construct contain full sequence or fragment of the target protein?

      2.2 Have you used any tagging which may interact with the recognition of the epitope?

      2.3 How have you selected the sequence of siRNA? Have you tried more than one SiRNA sequence? Could you check if the sequence corresponds correctly toDnmt3L protein?

      2.4 Have you checked the KO with Southern blot application?

      Thank you for your understanding and co-operation in this matter. I look forward to hearing from you and hope to solve this problem as soon as possible.

      Question

      Our customer has responded with the following;   Dear Abcam,   I really can’t waste any more time after something that is not relevant. I can’t waste anymore of my time putting and labeling figures to file a complaint, these figs can’t even make it to the paper, why should I be putting them together. I have run 3 westerns so far and 2 immunos and 1 ChIP, I seriously can’t afford any more time in this. DNMT3L was supposed to be the final bit in the paper and the most important part. The bands are at the perfect size. Gapdh at 37 and DNMT3L at 50 kD. hESCs and hIPSCs have been shown to express it so they are the positive control themselves. All we were looking for was difference in expression between disease and control human ips cells. Since we didn’t find any difference, we looked at localization where we were surprised to find it cytoplasmic. We looked again with different permeabilization protocols, still same results. Your AbReview shows DNMT3L to be nuclear which is correct and that’s how it should be, but its not in our case. So we stained negative control human fibroblast cell lines and again, staining was cytoplasmic where it should have been completely blank. Human fibroblasts can never express DNMT3L. Ofcourse, a secondary only control was used and it was blank, it is an obvious figure to attach, can’t be wasting my time doing it. Again, I can’t be wasting my time putting figures together in a paper like format when the stuff didn’t even work after spending months getting these cells to this stage and running these assays and finding out this. Antibody dilutions for IF have been used at 1:200 which is what is shown in the Abreview by a user for hESCs. Fits perfectly with our stuff. Should not have had a problem. We used BSA and milk both for westerns, BSA was shit and gave tons of background, 10% milk worked great.   I am sorry for the tone but I am extremely disappointed over this product. I have been a faithful abcam user bcoz it has been good with quality for which they demand expensive prices, but DNMT3L has been a bad experience. I can’t waste any more time in something that has not worked and I hope you understand. I demand a full-refund of the antibody purchased and replacement with a new and of course a different DNMT3L antibody that has some chance of being specific.   I wait for your response.   Kind Regards
