Hypoxia in tumors is closely associated with tumor aggressiveness and resistance to radio- and chemotherapeutic treatment. Therefore, reliable markers for hypoxia represent both valuable diagnostic markers and potential targets for therapeutic intervention.

Carbonic anhydrase IX, or CAIX, is a transmembrane protein whose expression is restricted to very few normal tissues, in particular the membranes of gastric mucosal epithelial cells. Under hypoxic conditions, hypoxia inducible factor-1 alpha (HIF-1a) is stabilized and the transcription factor HIF-1 transactivates the CA9 gene, resulting in expression of the CAIX protein in the hypoxic cells. CAIX is involved in both the extracellular acidification of hypoxic tumors, as well as the regulation of intracellular pH, making it an attractive target for therapies based on the manipulation of pH (Parks, et al., 2010). 

CAIX is considered to be one of the best cellular biomarkers of hypoxia. Furthermore, recent studies examining the association between CAIX levels and various clinicopathological outcomes suggest that CAIX expression may also be a valuable prognostic indicator for overall survival (Kirkpatrick et al., 2008; Jubb et al., 2009).

GeneTex is proud to introduce a superior monoclonal antibody against CAIX that has been fully validated through immunohistochemistry, immunofluorescence, western blotting and FACS.
