Spatial distribution of platelets and FXai in HB-Tie2-GFP mice. Confocal images of endothelium defined by GFP fluorescence (green) Alexa647-FXai (cyan) and Alexa555-anti-CD41 (red) at approximately 3 minutes without (-) FV-810SYA or after infusion of unlabeled FV-810SYA. Step size = 2 µm in z-plane, total sections = 20 µm. Bar represents 30 µm.
