Expression of Na+/Ca2+ exchanger 1 (NCX1) in rats with pMCAO and sham operated control rats. (A) Immunoblot with affinity purified anti-NCX1 antibody, revealing a 120 KDa product. (B) Densitometric analysis revealed that focal cerebral ischemia produced a significant increase of NCX1 expression in the ischemic penumbra 24 h after pMCAO compared with sham-operated rats (144±2%, n=4, *P<0.05).
