(B) SARS-CoV-2 isolate (hCoV-19/Italy) was pre-treated for 30 min at 37°C with either LMWH enoxaparin (250 IU/mL) or one of the following neutralizing antibodies (COVA1-18, 1-21 and 2-15), a non-neutralizing antibody (COVA1-27) or a human IgG1 isotype control, all at the concentration of 1 pg/mL. SARS-CoV-2 isolate alone or with blocks was added at a concentration of 100 TICD/mL. Detection of virus binding to Syndecan 1 expressing Namalwa was measured by quantitative real-time PCR. Data information: Data show the mean values and error bars are the SEM. Statistical analysis was performed using ordinary one-way with Tukey's multiple-comparison test. *P≤0.05, **P≤0.01 (n=2 measured in duplicates).
