  • Function

    Critical component of the membrane-bound oxidase of phagocytes that generates superoxide. It is the terminal component of a respiratory chain that transfers single electrons from cytoplasmic NADPH across the plasma membrane to molecular oxygen on the exterior. Also functions as a voltage-gated proton channel that mediates the H(+) currents of resting phagocytes. It participates in the regulation of cellular pH and is blocked by zinc.
  • Involvement in disease

    Defects in CYBB are a cause of chronic granulomatous disease X-linked (XCGD) [MIM:306400]. Chronic granulomatous disease is a genetically heterogeneous disorder characterized by the inability of neutrophils and phagocytes to kill microbes that they have ingested. Patients suffer from life-threatening bacterial/fungal infections.

Customer reviews and Q&As


Thank you for contacting us and your interest in our products.

I have had a look into this and there has been an error on our part. The antibody ab131083 was assigned the incorrect target (DUOX2) when it is actually raised against human NOX2. This is why the Western blot does not correspond to the DUOX2 predicted size. We have now amended this. Thank you for pointing this out to us. We have made all customers who have purchased this antibody aware of this.

We do have an alternative antibody raised against DUOX2. This is the rabbit polyclonal ab65813. This has been used in Western blotting with rat and human samples. If you would like to try the antibody in any other applications or species of samples you may be eligible for the Abtrial testing scheme. More information on this can be found from the following link:


If you would be interested in taking part in this scheme please let me know how you intend to use the antibody.

I hope this information has been of help. If you have any further questions, please do not hesitate to let me know.
