... (the Atlantic stingray, Dasyatis sabina ) and determine if V-H + -ATPase and Na + /K + -ATPase are expressed in the same cells. We found that gills from freshwater stingrays had the highest relative abundance of V-H + -ATPase and greatest number of V-H + -ATPase-rich cells, using immunoblotting...

...Peter M. Piermarini; David H. Evans ABSTRACT Changes in Na + /K + -ATPase activity and abundance associated with environmental salinity were investigated in the gills and rectal gland of the Atlantic stingray Dasyatis sabina . Using a ouabain-specific ATPase assay and western blotting, we found...
