Comparing the immunohistochemical localization of Na, K-ATPase "α" subunits in normal, BPH and PCa tissues using a pan α monoclonal antibody (mAb9A7) that recognizes all known α isoforms. The pan α monoclonal antibody produces a staining pattern which is identical to the α1 specific antibodies providing further evidence for the predominance of α1 expression in the prostate and the downregulation of Na, K-ATPase in PCa.
