(A) Expression of ACE2 in different cell lines probed with anti-ACE2 antibodies (AF933, 1:1000 dilution, 0.5 µg/mL). Expression of ACE2 (*; red) in BHK21 cells untransfected or transfected with human ACE2 construct (positive control, left panel) and various other cell lines showing expression in ARPE-19 cells (right panel). (B) Blocking ACE2 does not affect pseudovirion uptake at MOI 10 in ARPE-19 cells. Fold difference in uptake of pseudovirions in the presence of 1:500 dilution (1 µg/mL) and 1:250 dilution (2 µg/mL) of AF933 ACE2 antibody after 24 h incubation. **** p < 0.0001, ns—p > 0.05.
