MA3-930 detects sodium/potassium ATPase beta 1 from mouse, human, sheep, canine, and pig tissues. This antibody does not recognize the beta 1 or beta 2 subunit in rat.
MA3-930 has been successfully used in Western blot and immunohistochemistry and immunocytochemistry procedures. By Western blot, this antibody detects an ~42 kDa protein in liver samples and ~55 kDa in kidney samples representing beta sodium/potassium ATPase in sheep liver extract. Immunohistochemical staining of the sodium/potassium ATPase with MA3-930 yields a pattern consistent with plasma membrane localization.
The MA3-930 antigen is purified lamb kidney sodium/potassium ATPase beta. This antibody recognizes and epitope between amino acid residues 195-199 of sheep sodium/potassium ATPase beta 1.
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 a tissue-specific and developmental pattern 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.
