Flow Cytometry assay shows that SARS-CoV-2 S1 protein, Mouse IgG2a Fc Tag (Cat. No. S1N-C5257) can bind to HEK293/Human ACE2 Overexpression Stable Cell Line (Cat. No. CHEK-ATP042). The concentration of S1 used is 20 μg/mL (QC tested).
Paguma larvata ACE2, His Tag (Cat. No. AC2-P5248) immobilized on CM5 Chip can bind SARS S protein RBD, His Tag (Cat. No. SPD-S52H6) with an affinity constant of 0.101 μM as determined in a SPR assay (Biacore T200) (QC tested).
Paguma larvata ACE2, His Tag (Cat. No. AC2-P5248) immobilized on CM5 Chip can bind SARS-CoV-2 S protein RBD, His Tag (Cat. No. SPD-C52H3) with an affinity constant of 29 μM as determined in a SPR assay (Biacore T200) (Routinely tested).
Angiotensin-converting enzyme 2 (ACE2) is also known as ACEH (ACE homolog), is an integral membrane protein with considerable homologous to ACE, which belongs to the peptidase M2 family. ACE2 is an exopeptidase that catalyses the conversion of angiotensin I to the nonapeptide angiotensin, or the conversion of angiotensin II to angiotensin 1-7. ACE2 may be an important regulator of heart function. In case of human coronaviruses SARS and HCoV-NL63 infections, ACE-2 serve as functional receptor for the spike glycoprotein of both coronaviruses. ACE2 is activated by chloride and fluoride, but not bromide and Inhibited by MLN-4760, cFP_Leu, and EDTA, but not by the ACE inhibitors linosipril, captopril and enalaprilat. ACE2 is active from pH 6 to 9, and the optimum pH is 6.5 in the presence of 1 M NaCl.
