Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

This is the catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of sodium and potassium ions across the plasma membrane. This action creates the electrochemical gradient of sodium and potassium ions, providing the energy for active transport of various nutrients.
Gene References into Functions
  1. proof of concept study demonstrates that reduced expression of the alpha2 isoform in the spinal cord is protective following spinal cord injury PMID: 28886701
  2. Atp1a2 does contribute to alcohol-related behaviors, but the effect is modest with a clear dependence on sex. PMID: 27814792
  3. Atp1alpha2 is preferentially expressed with Atp1beta2 in T-tubules of cardiac myocytes, forming alpha2beta2 heterodimers. PMID: 27624940
  4. study provides evidence that muscle beta-catenin is crucial for maintenance of resting membrane potential(RMP)of skeletal muscle cells; muscle cells lacking beta-catenin show decreased expression of alpha2 subunit of Na,K-ATPase, a probable mechanism by which beta-catenin regulates RMP and affects normal function of skeletal muscle PMID: 24674304
  5. Heart expression of alpha2 does not play a role in the regulation of basal cardiovascular function or blood pressure; however, heart expression of alpha2 plays a role in the hypertrophic response to pressure overload. PMID: 23436327
  6. Atp1a2 has a more prominent role (vs. Atp1a1) in modulating cardiac myocyte sarcoplasmic reticulum Ca(2+) release. PMID: 22739122
  7. The ouabain-binding site of either the alpha1 or alpha2 Na,K-ATPase subunit does not play an essential role in the development of DOCA-salt hypertension in a mouse model PMID: 22258333
  8. Central sodium chloride causes hypertension in mice. The blood pressure response is mediated by the ouabain-like substance in the brain, specifically by its binding to the alpha(2)-isoform of the Na,K-ATPase. PMID: 21856907
  9. Atp1a2 expression in heart and vascular smooth muscle is not essential for regulation of basal systolic blood pressure. PMID: 21856916
  10. Ion channel NKCC1 and alpha2 Na, K-ATPase played important roles in the inner ear potassium recycling. PMID: 17111813
  11. Both protein and mRNA expression of alpha1 and alpha2 isoforms of Na,K-ATPase and NKCC1 in the lateral wall were dramatically reduced following a long-term deafening PMID: 21094218
  12. The cardiotonic steroid-binding site of the alpha2 Na,K-ATPase plays a role in maintaining normal SBP during pregnancy PMID: 20940714
  13. The Na,K-ATPase alpha(2) subunit is expressed during development when the t-tubules form. These results suggest that the alpha(2) isoform may serve, in part, a physiological role in the muscle t-tubules. PMID: 12397396
  14. Na,K-ATPase alpha2 isoform could be important in the modulation of neuronal activity in the neonate PMID: 12458206
  15. Ca2+ signaling is regulated by the expression of this protein as studied in knockout mice PMID: 12763872
  16. Heterozygote Atp1a2 mutant adult mice showed increased fear/anxiety behavior and enhanced neuronal activity in the amygdala and piriform cortex after conditioned fear stimuli; homozygotes died just post-birth and showed neuronal apoptosis in these regions PMID: 12805306
  17. the alpha2 Na,K-ATPase isozyme mediates ouabain-induced cardiac contractility in mice PMID: 14559919
  18. individual alpha-isoforms of the Na(+)/K(+)-ATPase differ functionally and that the alpha(2)-isoform couples more strongly to activation-relaxation pathways in vascular smooth muscle PMID: 14627611
  19. the alpha2-isoform of Na-K-ATPase mediates the ouabain-induced increase in vascular contractility and could play a role in the development and maintenance of ouabain-induced hypertension. PMID: 15458945
  20. We propose a model for functional coupling between the Na+, K+-ATPase alpha2 subunit and KCC2, which excludes Cl- from the cytosol in respiratory center neurons. PMID: 15564586
  21. Accordingly, in salt-dependent hypertension, EOLC probably increases vascular resistance and blood pressure by reducing alpha2 Na(+) pump activity and promoting Ca(2)(+) entry via NCX in myocytes. PMID: 16166162
