NOX2/gp91phox is a 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. It 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. Defects in CYBB are a cause of X-linked chronic granulomatous disease (X-CGD). X-CGD is characterized by the failure of activated phagocytes to generate superoxide. Patients suffer from life-threatening bacterial/fungal infections.

FAQs for CYBB/NOX2 Antibody (NBP1-51928). (Showing 1 - 1 of 1 FAQ).

  1. We would like to use the CYBB (NOX2) antibody for Western blotting on rat heart samples. Please, suggest us an alternative solution, if you have any!
    • I have taken a look for an alternative antibody, and we do have NBP1-51928 available. It has been validated for use in Western Blot however we have not yet tested this with Rat. I have carried out a BLAST on a protein database called UniProt and I have found that the percentage homology between the human CYBB and rat CYBB is 92.0%. If you would like to test this species you may find our Innovators Reward Program of interest, where we reward customers for trying our antibodies in novel species and applications.
