[Uses] α2-Antiplasmin from human plasma has been used as a protease inhibitor to tre at human microvascular endothelial cells (HMEC-1) and demonstrate the role of factors responsible for endothelial cells detachment. It has also been used to study its effect on the release of proteolytic activity under reducing conditions in therapeutic human serum albumin-containing products with a new neoepitope endopeptidase immunoassay.
[Biological Activity] α2-Antiplasmin (α2AP) is an antifibrinolytic protein and an important inhibitor of plasmin. α2AP mediates clot formation by covalently cross-linking with the glutamine and the lysine residue of fibrin clot via activated factor XIII (FXIIIa). This prevents the clot from extreme degradation by plasmin. An inborn insufficiency of α2AP results in an autosomal recessive condition leading to a rare bleeding disorder. The severity of the bleeding condition is defined by the individualμs genetic variation. Studies show lower levels of α2AP associated with disseminated intravascular coagulation (DIC) and thrombolytic therapy. Elevated levels of α2AP have been reported in a patient with ischemic stroke.
