HEK293/ACE2 Stable Cell Line

Figure 1. FACS analysis of cell surface expression of ACE2 on HEK293 cells. HEK293/ACE2 cells (red) and negative control HEK293 cells (green) were stained with SARS-CoV-2 Spike protein (RBD, His Tag) (Cat. No. Z03479, GenScript).

Figure 2. Cell-based binding assay of SARS-CoV-2 spike protein RBD with HEK293/ACE2 cells. HEK293/ACE2 cells were incubated with SARS-CoV-2 Spike protein (RBD, His Tag) (Cat. No. Z03479, GenScript) in serial dilution. Then the cells were stained with THE™ His Tag Antibody [iFluor 488] Mouse (Cat. No. A01800, GenScript) and analyzed with flow cytometer. FACS analysis shows the EC50 of spike protein RBD binding with ACE2 on HEK293 cells is 1.07 ug/ml.

Figure 3. Neutralization assay of SARS-CoV-2 spike protein RBD by ACE2-Fc fusion proteins on HEK293/ACE2 cells. HEK293/ACE2 cells were incubated with 1 µg/ml SARS-CoV-2 Spike protein (RBD, His Tag) (Cat. No. Z03479, GenScript) and ACE2-Fc fusion protein (Cat. No. Z03484, GenScript) in serial dilution. Then the cells were stained with THE™ His Tag Antibody [iFluor 488], (Cat. No. A01800, GenScript) and analyzed with flow cytometer.

Figure 5. FACS analysis of cell surface expression of ACE2 on HEK293 cells of different passages. The HEK293/ACE2 cells and the negative control HEK293 cells were stained with Spike protein (RBD, His Tag) (Cat. No. Z03479, GenScript). P8, P13, P17 and P21 are cell passage numbers.

HEK293/ACE2 Stable Cell Line

Recombinant HEK293 cells stably express Angiotensin-converting enzyme 2 (ACE2) on the cell surface. The surface expression of ACE2 is validated by FACS analysis. This stable cell line product is designed for cell-based binding assays that measure the binding affinity and stability of antibody based biologics binding with ACE2, and can be utilized for SARS-Cov-2 pseudovirus neutralization assay for screening neutralizing antibodies.
