rat kidney Na+/K+ ATPase.

General description

Epitope mapping studies indicate the antibody binds within the intracellular region at or near Asp-369 of the α subunit. Staining is consistent with the plasma membrane localization of Na+/K+ ATPase.

Mouse Monoclonal Anti-Na+/K+ ATPase (α1 Subunit) antibody localizes the Na+/ K+ ATPase α1 subunit in human, canine, rat and avian tissues.

Na+/K+ transporting ATPase subunit α1 is an ion transport pump critical for maintaining the gradient of Na and K ions across the plasma membrane.

Physical form

Solution in phosphate buffered saline containing 0.05% sodium azide.


Mouse Monoclonal Anti-Na+/K+ ATPase (α1 Subunit) antibody has been used for immunohistochemical assays. It has also been used for immunolabeling assays to quantify the expression of proteins involved in cellular ion transport. Furthermore, the product is suitable for use in indirect ELISA.
