ATP1B1Protein Product Information
Synonym:ATP1B1, ATP1B
Protein Construction:A DNA sequence encoding the human ATP1B1 (P05026-1) (Glu63-Ser303) was expressed with an N-terminal polyhistidine tag.
Species:Human
Expressed Host:Human Cells
Form & Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
ATP1B1Protein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:His
Molecule Mass:The recombinant human ATP1B1 comprises 261 amino acids and has a predicted molecular mass of 30.4 kDa. The apparent molecular mass of the protein is approximately 40-47 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Formulation:Lyophilized from sterile PBS, pH 7.4.
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
ATP1B1Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

Background

ATP1B1 belongs to the family of Na+/K+ and H+/K+-ATPases beta chain proteins, and to the subfamily of Na+/K+ -ATPases. ATP1B1 is a subunit of Na+/K+-ATPase. Na+/K+-ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. Na+/K+-ATPase is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). ATP1B1 regulates, through assembly of alpha/beta heterodimers, the number of sodium pumps transported to the plasma membrane. ATP1B1 is the non-catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with which catalyzes the hydrolysis of ATP coupled with the exchange of Na+ and K+ ions across the plasma membrane.
