Fig. 3aMean TM levels from GMVEC lysates. Spike proteins or serum-free media alone (as a control) were added to GMVECs for 48 h. Cell lysates were then collected, and TM was quantified by ELISA.

Fig. 3b. Mean APC levels in GMVEC supernatant. Spike proteins or serum-free media alone (as a control) were added to the cells for 48 h. Then PC and thrombin were added to the cells for 1 h, after which further reaction was prevented by addition of hirudin. Supernatant was collected for measurement of APC by ELISA. Fig. 3c. Mean Ba levels in GMVEC supernatant. Spike proteins or serum-free media alone (as a control) were added to the cells for 48 h. Supernatant was collected for measurement of Ba by ELISA.
