Angiotensin converting enzyme 2 or ACE-2 is an enzyme that is located in the cell membranes in different organs such as kidney, intestines, lungs, heart & arteries. ACE2 acts as an entry receptor of SARS coronaviruses & SARS-CoV-2.The coronavirus spike (S) glycoprotein is a class I viral fusion antigen bound to the external envelope of the virion that has a role in a crucial part in viral infection by identifying host cell receptors and starting fusion of the viral and cellular membranes. Couple of main domains in coronavirus S1 have been identified, the N-terminal domain and C-terminal domain. One or the other and/or both S1 domains acts as a receptor-binding domain. SARS-CoV + MERS-CoV equally use C-domain to attach their receptors.ACE2 is a type I transmembrane antigen with an extracellular N-terminal domain having the catalytic site and an intracellular C-terminal tail. ACE2 has a signal peptide, a transmembrane domain & a single metalloproteinase active site holds an HEXXH zinc-binding domain. ACE-2 takes part as a mono-carboxypeptidase which degrades Ang I to produce the nonapeptide Ang 19 and Ang II to create the heptapeptide Ang 17.
ACE2 Rat produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 731 amino acids (18-740 aa) and having a molecular mass of 84.7kDa. ACE2 is fused to an 8 amino acid His-Tag at C-terminus and purified by proprietary chromatographic techniques.
|Purification :||Greater than 95.0% as determined by SDS-PAGE.|
|Content :||The ACE2 solution contains 10% Glycerol and Phosphate-Buffered Saline (pH 7.4).|
|Storage condition :||Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.|
