Western Blot Analysis:
0.05-0.1 µg/mL of this lot detected the α-1 subunit in 20 µg of rat brain microsomal preparation (Catalog # 12-144). To reduce background, wash the blot with 0.05% Tween-20 in PBS for 15 minutes.

Target description

112 kDa

Analysis Note

Alpha 1 mRNA is present in all cell types examined.


2 µg of a previous lot immuno-precipitated the α-1 subunit from rat brain microsomal preparations.

1-10 µg/mL of a previous lot of this antibody was used in immunohistochemistry on ice-cold methanol-fixed tissue.

1. Do not boil microsomes. Warming to 37ºC for 15 minutes is recommended.
2. Microsomes from some tissues may contain sodium pump subunits which are below the level of detection by this antibody.
3. Microsomes derived from tissues which are more difficult to prepare, such as smooth and skeletal muscle, frequently show non-specific cross-reactivity.

General description

Na+/K+-ATPase (also known as the Na+/K+ pump or sodium-potassium pump) is an enzyme located in the plasma membrane (specifically an electrogenic transmembrane ATPase). It is found in the plasma membrane of virtually every human cell and is common to all cellular life. It helps maintain cell potential and regulate cellular volume.
In order to maintain the cell potential, cells must keep a low concentration of sodium ions and high levels of potassium ions within the cell (intracellular). Outside cells (extracellular), there are high concentrations of sodium and low concentrations of potassium, so diffusion occurs through ion channels in the plasma membrane. In order to keep the appropriate concentrations, the sodium-potassium pump pumps sodium out and potassium in through active transport.
