Note: The complete
sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is
translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application,
please explicitly request the full and complete sequence of this protein before ordering.
Tag Info
C-terminal hFc1-tagged
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.
Form
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
Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
Reconstitution
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.
Storage Condition
Store at -20°C/-81°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Lead Time
3-7 business days
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.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, storage temperature and the stability of the product itself. Generally, the shelf life of lyophilized form is 6 months at -20°C/-80°C from the date of receipt.

Description
ACE2 serves as the primary receptor for SARS-CoV-2 spike protein entry, making this cynomolgus monkey ortholog a critical tool for translational studies bridging preclinical primate models and human infection biology. This recombinant construct spans residues aa 18–741, expressed in mammalian cells with a C-terminal hFc1 tag positioned to preserve the catalytic domain, and its binding activity has been validated by functional ELISA demonstrating an EC50 of 5.638–9.496 ng/ml against immobilized SARS-CoV-2 S1-RBD, confirming robust receptor–ligand interaction suitable for inhibitor screening, IC50 determination, and drug candidate evaluation studies. The confirmed binding competence also supports use as a positive control in enzyme-linked assays, while the protein provides a suitable basis for substrate specificity profiling and kinetic parameter analysis (Km, Vmax, kcat). Purity exceeding 90% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg meets the quality thresholds commonly required for accurate kinetic measurements and cell-based functional assays.
