Streptokinase, β-hemolytic streptococcus (Lancefield Group C)（Cat No.:I044245）is a bacterial-derived protein that acts as a potent fibrinolytic agent by activating plasminogen to plasmin, which dissolves fibrin clots. Isolated from β-hemolytic streptococcus of Lancefield Group C, this form of streptokinase is used in thrombolytic therapy to treat conditions such as myocardial infarction, pulmonary embolism, and deep vein thrombosis. It is also a valuable tool in clot dissolution studies and cardiovascular research. Its ability to promote clot breakdown makes it essential in both clinical settings and experimental models of fibrinolysis and hemostasis.
