Andere Bezeichnung: Factor XIIIa

Hintergrund: F13A1 Antibody for IHC recognizes Coagulation factor XIII A, the catalytic transglutaminase subunit encoded by the F13A1 gene on chromosome 6p25.1. Coagulation factor XIII A, also referred to as Factor XIIIa or Factor XIII A chain, is a cytoplasmic enzyme expressed in platelets, macrophages, dermal dendritic cells, and selected stromal populations. Upon activation by thrombin and calcium, the inactive zymogen is cleaved to generate active Factor XIIIa, which catalyzes covalent cross-linking of fibrin monomers. This reaction stabilizes the fibrin clot and confers resistance to fibrinolysis, representing the final enzymatic step of the coagulation cascade.

Coagulation factor XIII A belongs to the transglutaminase family and contains a catalytic core domain that mediates formation of epsilon-gamma glutamyl-lysine isopeptide bonds between substrate proteins. In plasma, factor XIII circulates as a heterotetramer composed of two catalytic A subunits and two non-catalytic B subunits. Following thrombin-mediated activation, the B subunits dissociate and the A subunits become enzymatically active. Beyond clot stabilization, Factor XIIIa contributes to extracellular matrix remodeling by cross-linking fibronectin, collagen, and other structural proteins, supporting wound healing and tissue repair processes.

In normal tissues, Coagulation factor XIII A expression is prominent in dermal dendrocytes and tissue macrophages. It is also detectable in placenta and bone marrow-derived cells. In fibrohistiocytic lesions, F13A1 Antibody for IHC is frequently applied in research settings to help characterize dermatofibroma, which typically demonstrates strong cytoplasmic positivity in spindle-shaped dermal cells, whereas dermatofibrosarcoma protuberans generally lacks staining. Expression patterns have also been described in inflammatory and reparative conditions involving macrophage activation and stromal remodeling.

Inherited deficiency of Factor XIII results in impaired clot stability and delayed wound healing, underscoring the biologic importance of F13A1 function. Altered expression has been observed in inflammatory and fibrotic disorders, reflecting its broader role in immune cell biology and extracellular matrix stabilization. Clone MSVA-813R is a rabbit monoclonal antibody suitable for detecting Coagulation factor XIII A expression in immunohistochemistry and related research applications, where staining is typically cytoplasmic in dendritic or macrophage-lineage cells.
