Used for the quantitative measurement of SK (Streptokinase) activity in human serum, plasma, or other biological fluids. This ELISA kit is widely applied in clinical research and diagnostics to assess fibrinolytic activity, monitor thrombolytic therapy, and study conditions related to blood clotting and dissolution. It enables researchers to evaluate the functional levels of SK in samples, supporting investigations into cardiovascular diseases, stroke, and the effectiveness of clot-busting treatments. The assay is suitable for high-throughput analysis in laboratories focused on hemostasis and thrombosis research.
