FN1 and alkaline phosphatase measurement: In general, the studied trout from farm A were characterised by an altered expression of haemostatic and fibrinolytic proteins (Figure 4C), with isoforms of fibrinogen (A0A060XZH2, A0A060YWY3), fibronectin (A0A060YV80), alpha-2-antiplasmin (A0A060XQ45), kininogen (A0A060WI78), and plasminogen (A0A060W7T7) down-regulated and alpha-1-microglobulin/bikunin precursor AMBP (A0A060YC43), haemagglutinating lectin (A0A060W1N4), and coagulation factor XIII B (A0A060YM30) up-regulated in AP.
