Recombinant Human ATP4a, His-tagged

• Cat.No.: ATP4a-3765H
• Product Overview: ATPase, H+/K+ Exchanging Alpha Polypeptide (ATP4a)

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 1035
• Description: The protein encoded by this gene belongs to a family of P-type cation-transporting ATPases. The gastric H+, K+-ATPase is a heterodimer consisting of a high molecular weight catalytic alpha subunit and a smaller but heavily glycosylated beta subunit. This enzyme is a proton pump that catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. It is also responsible for gastric acid secretion. This gene encodes a catalytic alpha subunit of the gastric H+, K+-ATPase.
• Form: Supplied as lyophilized form in PBS,pH7.4, containing 5% sucrose, 0.01% sarcosyl.
• Molecular Mass: 12.7kDa
• Endotoxin: <1.0eu per 1ug (determined by the lal</1.0eu
• Purity: >95%
• Applications: SDS-PAGE, Western Blot (WB), ELISA (EIA), Immunoprecipitation (IP)
• Notes: Small volumes of ATP4a recombinant protein may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice.
• Storage: Avoid repeated freeze/thaw cycles. Store at 2-8 degree C for one month. Aliquot and store at -80 degree C for 12 months.Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test,that is, incubate the protein at 37 degree C for 48h, and no obvious degradation andprecipitation were observed. (Referring from China Biological Products Standard,which was calculated by the Arrhenius equation.) The loss of this protein is lessthan 5% within the expiration date under appropriate storage condition.
• Reconstitution: Reconstitute in sterile PBS, pH7.2-pH7.4.
• Warning: This product is for research use only. Not for use in diagnostic or therapeutic procedures.
