Am J Physiol Regulatory Integrative Comp Physiol 280: R1844–R1852, 2001. Gill Na �-K �-2Cl � cotransporter abundance and location in Atlantic salmon: effects of seawater and smolting
abundance and location was examined in the gills of Atlantic salmon (Salmo salar) during seawater acclimation and smolting. Western blots revealed three bands centered at 285, 160, and 120 kDa. The Na�-K�-2Cl � cotransporter was colocalized with Na�-K�-ATPase to chloride cells on both the primary fi...
