Figure Lengend Snippet: (A-C) Neutralization of infectious SARS-CoV-2 following incubation with two-fold dilutions of rCL-11 (black) in A549-hACE-2 cells (starting at 40 µg/ml) (A) , Calu-3 cells (starting at 20 µg/ml) (B) , and Huh7.5 cells (starting at 20 µg/ml) (C) using the conventional experimental setup. The mAb clone 61 was used as a neutralization control (orange) and rCL-11 buffer (gray) in corresponding dilutions was used to monitor buffer-mediated effects on the cells. The percentage of protected cells was determined from the number of SARS-CoV-2 infected cells in experimental wells compared to the number of infected cells in virus-only control wells after anti-S protein immunostaining. Data are shown as means ± SD of four (A549-hACE-2 and Calu-3 cells) or six (Huh7.5 cells) replicates.
Article Snippet: The human lung adenocarcinoma A549-hACE-2 cell line (InvivoGen, San Diego, California, USA) (A549 cells expressing human ACE-2) was maintained as described previously [ ].
