Preparation Note Download the IFU specific to your product lot and format Note: This requires a keycode which can be found on your packaging or product label. Coagulation factor XIII is the last zymogen to become activated in the blood coagulation cascade. Plasma factor XIII is a heterotetramer composed of 2 A subunits and 2 B subunits.

El factor de coagulación XIII, factor XIII, factor estabilizador de la fibrina o factor de Laki-Lorand es una proteína plasmática de síntesis hepática y plaquetaria, que participa en la ruta final común de la hemostasia, estabilizando el coágulo blando de fibrina o polímero de fibrina

Validated in WB, ICC/IF, IHC-P. Tested in Human, Mouse. Cited in 1 reference(s). Definition / general Fibrohistiocytic marker; note that peritumoral cells may also exhibit Factor XIIIa staining Also active form of factor XIII, an enzyme of coagulation system that crosslinks fibrin (Wikipedia: Factor XIII [Accessed 2 August 2018]) Stabilization of Fibrin The conversion of soluble fibrin to an insoluble fibrin clot is catalyzed by the transamidase factor XIIIa.

Human coagulation Factor XIIIa - Activated from Factor XIII by cleavage with human alpha thrombin. The thrombin is subsequently removed via chromatography.

Factor XIII is activated by thrombin in the presence of calcium which leads to the release of the activation peptide, followed by the dissociation of carrier subunits. The activated Factor XIII (XIIIa) acts on fibrin (Factor Ia) to form γ-glutamyl-Є-lysyl amide cross links between fibrin molecules leading to the formation of an insoluble clot. Factor XIII (FXIII), or fibrin stabilizing factor, deficiency was first reported in the literature in 1960. It is the rarest factor deficiency, occurring in 1 per 5 million births.

Factor XIIIa is a blood proenzyme that has been identified in platelets, megakaryocyte, and fibroblast-like mesenchymal or histiocytic cells present in the placenta, uterus, and prostate; it is also present in monocytes and macrophages and dermal dendritic cells. Factor XIII (FXIII), or fibrin stabilizing factor, deficiency was first reported in the literature in 1960.

Metoda – test de solubilizare a cheagului (se determina cea mai mare dilutie a plasmei la care un cheag, obtinut prin adaugarea de trombina si calciu la un fibrinogen exogen fara factor XIII, ramane insolubil in prezenta acidului cloroacetic) 4.

It is the rarest factor deficiency, occurring in 1 per 5 million births. It is inherited in an autosomal recessive fashion, meaning that both parents must carry the gene to pass it on to their children; it affects men and women equally. Factor XIIIa Activity Assay Kit (Colorimetric); Factor XIII or fibrin stabilizing factor (EC 2.3.2.13) is an enzyme involved in the blood coagulation system that crosslinks fibrin. Factor XIII is activated by thrombin in the presence of calcium which leads to the release of the activation peptide, followed by the dissociation of carrier subunits.

Factor XIIIaは、血液凝固因子の一つで、真皮の間質の樹枝状細胞や紡錘形細胞の一部で陽性となる。 皮膚科領域では、Dermatofibroma(DF)とDermatofibrosarcoma protuberans(DFSP)の鑑別に用いられる。

It can be used for histiocytic phenotyping and has been reported to mark capillary hemangiomas and tumors of the central nervous system (1-6). Factor XIIIa has also been used with CD34 to Factor XIIIa is a blood proenzyme that has been identified in platelets, megakaryocyte, and fibroblast-like mesenchymal or histiocytic cells present in the placenta, uterus, and prostate; it is also present in monocytes and macrophages and dermal dendritic cells. Platelet factor XIII is comprised only of 2 A subunits, which are identical to those of plasma origin. Upon cleavage of the activation peptide by thrombin and in the presence of calcium ion, the plasma factor XIII dissociates its B subunits and yields the same active enzyme, factor XIIIa, as platelet factor XIII.
