👉 Trout fluid, also known as cutlethin, is a naturally occurring anticoagulant found in the blood of trout and other freshwater fish. It functions by inhibiting thrombin, a crucial enzyme in the blood clotting process, thereby preventing the formation of blood clots. This property makes trout fluid valuable in medical research and applications, particularly in studying blood coagulation disorders and developing new anticoagulant therapies. Its ability to selectively target clotting factors without affecting other physiological processes makes it a promising candidate for use in treating conditions like deep vein thrombosis and pulmonary embolism, while minimizing the risk of bleeding complications.
