Immunohistochemistry was performed on human renal carcinoma tissue. To expose target protein, antigen was retreived using 10mM sodium citrate followed by microwave treatment for 8-15 minutes. Endogenous peroxidases were blocked in 3% H202-methanol for 15 minutes and tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a Sodium/Potassium ATPase mouse monoclonal antibody (Product # MA3-924) at a dilution of 1:10 overnight in a humidified chamber. Tissues were washed in PBST and detection was performed using a secondary antibody conjugated to HRP. DAB staining buffer was applied and tissues were counterstained with hematoxylin and prepped for mounting. Images were taken at 40X magnification.

MA3-924 detects the alpha 1 sodium/potassium ATPase in human, mouse, canine, rat and avian tissues.
MA3-924 has been successfully used in immunohistochemistry, immunocytochemistry, immunofluorescence, ELISA and immunoprecipitation procedures. Immunohistochemical staining of sodium/potassium ATPase in rat liver with MA3-924 yields a pattern consistent with plasma membrane localization. Immunoprecipitation of sodium/potassium ATPase from canine kidney extracts can be used for affinity purification of the alpha subunit. MA3-924 can also be utilized to inhibit activity of the enzyme.
The MA3-924 antigen is purified rat kidney sodium/potassium ATPase. This antibody recognizes an epitope within an intracellular region at or near Asp-369 of the sodium/potassium ATPase alpha subunit.
The sodium/potassium ATPase is an integral membrane enzyme found in all cells of higher organisms and is responsible for the ATP-dependent transport of sodium and potassium across the cell membrane. This membrane-bound enzyme is related to a number of other ATPases including sarcoplasmic and endoplasmic reticulum calcium ATPase (SERCA) and plasma membrane calcium ATPase (PMCA). The sodium/potassium ATPase consists of a large, multipass, transmembrane catalytic subunit, termed the alpha subunit, and an associated smaller glycoprotein, termed the beta subunit. Studies indicate that there are three isoforms of the alpha subunit (alpha 1, alpha 2, alpha 3) and two isoforms of the beta subunit (beta 1 and beta 2) encoded by two multigene families.
The different isoforms of the sodium/potassium ATPase exhibit tissue-specific and developmental patterns of expression. The alpha 1 and beta mRNAs are present in all cell types examined, whereas the alpha 2 and alpha 3 mRNAs exhibit a more restricted pattern of cell-specific expression. The alpha subunit has been found in kidney, brain, heart, and to a lesser extent liver, skeletal and smooth muscle.
