This antibody is expected to recognize both reported isoforms of Human beta Sodium Potassium ATPase (NP_001668.1; NP_001001787.1)This is the non-catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of Na(+) and K(+) ions across the plasma membrane. The beta subunit regulates, through assembly of alpha/beta heterodimers, the number of sodium pumps transported to the plasma membrane.Store at 4°C short term (1-2 weeks). Aliquot and store at -20°C long term. Avoid repeated freeze / thaw cycles. *   http://www.creative-diagnostics.com/Anti-ATP1B1-PAb-198224-147.htm
