Application Notes
This Dnmt3b antibody is useful for Immunocytochemistry/Immunofluorescence, Immunohistochemistry on paraffin-embedded sections, Immunoprecipitation and Western Blot, where a band is seen at ~100 kDa. This antibody does not neutralize the enzymatic activity of its corresponding methyltransferase. In ICC/IF, cytoplasmic staining was observed in NIH-3T3 cells. In IHC, predominant nuclear staining was observed, as well as some weaker cytoplasmic signal, in mouse testes. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Theoretical MW
100 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Owing to its critical role in long-term transcriptional silencing, DNA methylation represents a key layer of epigenetic information that is essential to biological processes such as embryonic development, germline differentiation, functional maturation of neuronal tissues etc. and DNA-methyltransferases family members (DNMT3A, DNMT3B and DNMT3L) have the ability to transfer methyl group derived from folate intermediates to nucleic acids. Among DNMTs, Dnmt3b [DNA (cytosine-5)-methyltransferase 3B] primarily functions in de novo DNA methylation and its expression is developmentally regulated. Dnmt3b is essential for establishment of DNA methylation patterns during development and may preferentially methylates nucleosomal DNA within the nucleosome core region. Independent of DNA methylation, Dnmt3b functions as transcriptional co-repressor by associating with CBX4, ZHX1 etc. In association with DNMT1 and via the recruitment of CTCFL/BORIS, Dnmt3b is involved in activation of BAG1 gene expression by modulating dimethylation of promoter histone H3 at H3K4 and H3K9. Mutations in DNMT3B have been linked to the immunodeficiency-centromeric instability-facial anomalies syndrome type 1 (ICF1).

FAQs for DNMT3B Antibody (NB100-266). (Showing 1 - 1 of 1 FAQs).

  1. I'd like to know if this antibody (catalog # NBP1-00783) is likely to cross-react with DNMT3a? Also, I'd like to use it to detect marsupial DNMT3b (XP_003757074.1) by WB and IHC-P. Is it likely to cross-react with this? Or with marsupial DNMT3a (XP_003757846)?
    • Our best antibody to Dnmt3b is NB100-266 but unfortunately, neither NB100-266 nor NBP1-00783 are predicted to cross-react with your species. NBP1-54350 is predicted to cross-react react with marsupial, but the immunogen also shares 86% identity with human and marsupial Dnmt3a. NBP1-54350 would have to be the antibody I most recommend.
