Target

  • Function
    Constitutive NADPH oxidase which generates superoxide intracellularly upon formation of a complex with CYBA/p22phox. Regulates signaling cascades probably through phosphatases inhibition. May function as an oxygen sensor regulating the KCNK3/TASK-1 potassium channel and HIF1A activity. May regulate insulin signaling cascade. May play a role in apoptosis, bone resorption and lipolysaccharide-mediated activation of NFKB. May produce superoxide in the nucleus and play a role in regulating gene expression upon cell stimulation. Isoform 3 is not functional. Isoform 4 displays an increased activity. Isoform 5 and isoform 6 display reduced activity.
  • Tissue specificity
    Expressed by distal tubular cells in kidney cortex and in endothelial cells (at protein level). Widely expressed. Strongly expressed in kidney and to a lower extent in heart, adipocytes, hepatoma, endothelial cells, skeletal muscle, brain, several brain tumor cell lines and airway epithelial cells.
  • Sequence similarities
    Contains 1 FAD-binding FR-type domain.
    Contains 1 ferric oxidoreductase domain.
  • Developmental stage
    Expressed in fetal kidney and fetal liver.
  • Post-translational
    modifications
    Isoform 3 and isoform 4 are N-glycosylated. Isoform 4 glycosylation is required for its proper function.
  • Cellular localization
    Endoplasmic reticulum membrane. Cell membrane. Cell junction > focal adhesion. Nucleus. May localize to plasma membrane and focal adhesions. According to PubMed:15927447, may also localize to the nucleus.

Question
Answer

Thank you for contacting Abcam.



After having talked with the lab, we agree that your data looks good. I see that there is a band near 63 KDa (the expected molecular weight) with all of the antibodies and even in couple of your blots there looks to small increases in expression levels in your transfected lanes.


Unfortunately, we do not have QC data that we can send to show specificity, however, two of these antibodies (ab109225 (3187-1) & ab133303 (#3174-1) ) were produced as part of a collaboration and they ran controls to verify that the antibody is specific to NOX4. I would refer you to the Results section of the following publication because they state that the antibody has been confirmed to be specific ("Using lysates from both Nox4 overexpressing cells and cells from Nox4 knockout mice, we confirmed the specificity of both the rabbit polyclonal (not shown) and monoclonal Nox4 antibodies"):



Lee, C.F., Qiao, M. Schroeder, K., Zhao, Q. and Asmis, R., Nox4 is a novel inducible source of reactive oxygen species in monocytes and macrophages and mediates oxidized low density lipoprotein-induced macrophage death. ,Circ.Res. 106(9): 1489-97 (2010).



If after looking at this paper, you still do not agree with the results, then please let me know and I will process a refund.



Please let me know if you have any further questions.

Answer

Thank you for contacting us.

This product was developed by one of our collaborator university laboratory. They are having difficulties in product so the product is unpublished momentarily.

The product ab109225 is a rabbit monoclonal antibody against NOX4 and is a different product. I would suggest trying this product as alternative.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Answer

Thank you for contacting us.
I am sorry to hear that the antibody is not working as stated on the datasheet.

As we discussed over the phone, I would suggest the following:
1) load more protein (e.g. 30- 50 ug) use more antibody
2) use more primary antibody (e.g. 1/500)

Please let me know if these tips are of help or not.
If not, I'd be happy to discuss other options to resolve this problem if the antibody was purchased within the last 6 months.

I wish you good luck and look forward to hear back from you.
