Figure 1.

Verification of membrane protein purification using Western blotting analysis. Blots were probed with anti-Na+/K+-ATPase for the plasma membrane and anti-prohibitin for mitochondria. T-M and T-C indicate the solution of membrane proteins and the solution of cytoplasm proteins in tumor tissue, respectively. N-M and N-C indicate the solution of membrane proteins and the solution of cytoplasm proteins in normal lung tissue, respectively.
