Western blot of NM0161 immunoprecipitates (IP) and whole lysates. The NM0161 antibody only (lane 1), IP from A431 cell lysate (lane 2), A431 cell input (lane 3), LNCaP cells (lane 4), MeWo cells (lane 5), and normal human lung (lane 6) and skin (lane 7). The blot was probed with anti-Na+/K+ ATPase β3 NM0161 (lanes 1-7). The arrow designates native antibody, while the β3 subunit migrates around 40 kDa.
