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.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is 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°C/-80°C. 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
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

CUSABIO used E.coli cells to express N-terminal 6xHis-SUMO-tagged Human ATP synthase subunit alpha, mitochondrial (ATP5F1A). This recombinant ATP5F1A protein is full-length of mature protein containing 44-553aa of human ATP5F1A. It underwent validation via LC-MS/MS analysis. Its purity reached up to 90% determined by SDS-PAGE. Under reducing conditions, a molecular weight band of around 87 kDa was visualized on the gel. In-stock ATP5F1A proteins are offered now. This recombinant ATP5F1A protein may discover uses in the specific antibody production or the studies of ATP5F1A-associated metabolism.

ATP5F1A, the matrix-exposed sector of ATP synthase, is the non-catalytic subunit that can bind to an Mg2+ and a nucleotide. ATP synthase not only synthesizes ATP but is also critical for the architecture of the mitochondrial inner membrane.

Target Background

Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Subunits alpha and beta form the catalytic core in F(1). Rotation of the central stalk against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits. Subunit alpha does not bear the catalytic high-affinity ATP-binding sites. Binds the bacterial siderophore enterobactin and can promote mitochondrial accumulation of enterobactin-derived iron ions.
