Immunofluorescent analysis of sodium/potassium ATPase alpha-1 (green) in HeLa cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 15 minutes at room temperature and blocked with 0.3% BSA for 15 minutes at room temperature. Cells were probed with a sodium/potassium ATPase alpha-1 monoclonal antibody (Product # MA3-929) at a dilution of 1:100 for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody (Product # 35502) at a dilution of 1:500 for 30 minutes at room temperature. F-actin (red) was stained with DyLight 594 Phalloidin (Product # 21836) and nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ArrayScan Instrument at 20X magnification.

MA3-929 detects sodium/potassium ATPase alpha 1 in sheep, canine, rat, mouse, human and porcine tissues. This antibody does not detect the alpha 1 isoform in Xenopus and chicken. MA3-929 does not detect the alpha 2 or alpha 3 isoform in rat.
MA3-929 has been successfully used in Western blot, immunofluorescence, immunocytochemistry, flow cytometry, and immunohistochemistry procedures. By Western blot, this antibody detects an ~110 kDa protein representing alpha 1 sodium/potassium ATPase from canine kidney extract. Immunohistochemical staining of sodium/potassium ATPase alpha 1 with MA3-929 yields a pattern consistent with plasma membrane localization.
The MA3-929 antigen is sheep kidney alpha 1 sodium/potassium ATPase. This antibody recognizes an epitope between amino acid residues 496-506 of lamb kidney sodium/potassium ATPase.
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.
