Anti-Beta 2 Na+/K+ ATPase (extracellular) Antibody (#ANP-012) is a highly specific antibody directed against an epitope of the rat ATP1B2. The antibody can be used in western blot analysis. The antibody recognizes an extracellular epitope, and could potentially be used for detecting the protein in living cells. It has been designed to recognize ATP1B2 from rat, mouse, and human samples.
