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.
Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
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.

The ACE2 protein CSB-MP684964PAL is a recombinant Paguma larvata ACE2 produced in mammalian cells, with a C-terminal hFc-tag. Its expression region corresponds to amino acids 18-740 of the Paguma larvata ACE2 protein. This recombinant ACE2 protein is biologically active, low in endotoxin (less than 1.0 EU/µg protein, determined by the LAL method), and high in purity (greater than 90%, SDS-PAGE). In the functional ELISA, SARS-CoV-2 S-RBD can bind to this ACE2 protein binds to the anti-ACE2 antibody with an EC50 constant of 5.056-7.559 ng/ml. Its enzyme activity was determined by cleaving fluorogenic peptide substrate, with the Km of 22.84 nM. It is available now.

ACE2 is a zinc metalloenzyme and carboxypeptidase that negatively regulates the renin-angiotensin system (counterbalancing ACE activity), acts as the key SARS-CoV and SARS-CoV0-2 receptor, and stabilizes the transport of the neutral amino acids.

Target Background

Essential counter-regulatory carboxypeptidase of the renin-angiotensin hormone system that is a critical regulator of blood volume, systemic vascular resistance, and thus cardiovascular homeostasis. Converts angiotensin I to angiotensin 1-9, a nine-amino acid peptide with anti-hypertrophic effects in cardiomyocytes, and angiotensin II to angiotensin 1-7, which then acts as a beneficial vasodilator and anti-proliferation agent, counterbalancing the actions of the vasoconstrictor angiotensin II. Also removes the C-terminal residue from three other vasoactive peptides, neurotensin, kinetensin, and des-Arg bradykinin, but is not active on bradykinin. Also cleaves other biological peptides, such as apelins, casomorphins and dynorphin A. Plays an important role in amino acid transport by acting as binding partner of amino acid transporter SLC6A19 in intestine, regulating trafficking, expression on the cell surface, and its catalytic activity.; (Microbial infection) Acts as a receptor for human coronavirus SARS.
