Application Abreviews Notes
IHC-P 1/2000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF Use at an assay dependent concentration. PubMed: 22184405
WB Use a concentration of 1 µg/ml. Detects a band of approximately 65 kDa (predicted molecular weight: 65 kDa).


  • FunctionCritical 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 diseaseDefects 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.

I wanted to answer your question about the two band at different MW.

The difference in MW for the two WBs for ab31092 is due to one
being run on a partial recombinant protein (15 kDa) and the other being run on
endogenous lysates (6...
