Flow Cyt Use 1µg for 106 cells.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.



  • Function
    Required for genome wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. DNA methylation is coordinated with methylation of histones. It modifies DNA in a non-processive manner and also methylates non-CpG sites. May preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1. Plays a role in paternal and maternal imprinting. Required for methylation of most imprinted loci in germ cells. Acts as a transcriptional corepressor for ZNF238. Can actively repress transcription through the recruitment of HDAC activity.
  • Tissue specificity
    Highly expressed in fetal tissues, skeletal muscle, heart, peripheral blood mononuclear cells, kidney, and at lower levels in placenta, brain, liver, colon, spleen, small intestine and lung.
  • Sequence similarities
    Belongs to the C5-methyltransferase family.
    Contains 1 ADD domain.
    Contains 1 GATA-type zinc finger.
    Contains 1 PHD-type zinc finger.
    Contains 1 PWWP domain.
  • Domain
    The PWWP domain is essential for targeting to pericentric heterochromatin.
  • Post-translational
    Sumoylated; sumoylation disrupts the ability to interact with histone deacetylases (HDAC1 and HDAC2) and repress transcription.
  • Cellular localization
    Nucleus. Cytoplasm. Accumulates in the major satellite repeats at pericentric heterochromatin.

  • ab13888 (2µg/ml) staining Dnmt3a in human testis using an automated system (DAKO Autostainer Plus). Using this protocol there is strong nuclear staining in the seminal vesicles.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

  • Overlay histogram showing HEK293 cells stained with ab13888 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab138889, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HEK293 cells fixed with 80% methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

Thank you for contacting Abcam.

It could be that ab13888, is recognizing a non-specific band in the cell lines that you are using, but you should still be seeing a band at about 100kDa.

To be able to help resolve this issue, could y...

Thank you for contacting Abcam.

I have attached the ppt slide with a red arrow next to the bands that I think are the correct bands(they are the same that you have marked).

There are a few protocol changes that I would recommend to ...
