(C, D) SARS-CoV-2 binding was measured in polarized Caco-2 (C) and Calu-3 (D) cells in presence or absence of antibodies against ACE2 (cell incubation), and UF heparin (250 IU/mL) or LMWH enoxaparin (250 IU/mL) (virus incubation). Data information: Data show the mean values and error bars are the SEM. Statistical analysis was performed using ordinary one-way ANOVA with Tukey's multiple-comparison test. *P≤0.05, **P≤0.01, ***P≤0.001, ****P≤0.0001 (C) (n=3 Caco-2 donors measured in triplicate), (D)(n=3 Calu-3 donors measured in triplicate)
