Used in clinical and research laboratories to quantitatively measure ADAMTS13 enzyme activity or antigen levels in human plasma. This kit is essential for diagnosing and monitoring thrombotic thrombocytopenic purpura (TTP), a rare but life-threatening disorder characterized by low ADAMTS13 activity. It enables researchers to study the role of ADAMTS13 in vascular biology, hemostasis, and inflammatory conditions. The assay supports investigation into autoimmune disorders, endothelial dysfunction, and thrombotic microangiopathies by providing a reliable method to assess protease deficiency or inhibition. Widely used in studies involving von Willebrand factor regulation and its cleavage under pathological conditions.
