(B) SARS-CoV-2 pseudovirus was pre-incubated for 30 min at 37°C with UF heparin (250 IU/mL) or LMWHs tinzaparin (250 IU/mL) or dalteparin (250 IU/mL) or LMWH enoxaparin (250 IU/mL) or nadroparin (250 IU/mL). Huh7.5 were exposed to the SARS-CoV-2 pseudovirus, alone or treated with different LMWHs for 4 hours at 4°C, washed, lysed and binding was determined by ELISA. (C) SARS-CoV-2 pseudovirus was pre-incubated for 30 min at 37°C with UF heparin (250 IU/mL) or LMWHs tinzaparin (250 IU/mL) or dalteparin (250 IU/mL) or LMWH enoxaparin (250 IU/mL) or nadroparin (250 IU/mL). Huh7.5 cells were infected with SARS-CoV-2 pseudovirus in presence or absence of different LMWHsSARS-CoV-2 and infection was determined after 5 days by luciferase reporter activity. Data information: Data show the mean values and error bars are the SEM. Statistical analysis was performed using (B) ordinary one-way ANOVA with Tukey's multiple-comparison test (n=3 donors measured in monoplo), (C) ordinary one-way ANOVA with Dunnett's multiple-comparison test. *P≤0.05, **P≤0.01, ***P≤0.001, ****P≤0.0001 (n=3 donors measured in triplicate)
