FIGURE 1. Experimental ECAT setup. Cannula is inserted into one of lateral tail veins (1) for return of blood and is connected to extracorporeal system (regulated by the pump (2)). For blood access, another cannula is inserted into ventral tail artery (3). When cannulas are inserted, extracorporeal circulation is begun in bypass mode (4) without column connected. Once the circuit is filled with blood and any air bubbles in circuit have been collected in the air trap (5), column (6) is connected to the circuit and affinity adsorption is begun.
