Factor XIIIa antibody is a diagnostic tool targeting the activated form of coagulation Factor XIII (FXIII), a key enzyme in hemostasis and tissue repair. FXIII circulates as a proenzyme (FXIII-A₂B₂) composed of two catalytic A-subunits (FXIII-A) and two carrier B-subunits (FXIII-B). Upon thrombin-mediated cleavage during clot formation, FXIII is activated to FXIIIa, which crosslinks fibrin polymers, stabilizing blood clots and enhancing wound healing. FXIIIa also interacts with extracellular matrix proteins, influencing tissue remodeling and angiogenesis.
FXIIIa antibodies, typically monoclonal, detect FXIII-A subunits in activated cells, aiding in histopathological studies. They are widely used in immunohistochemistry (IHC) to identify FXIIIa-positive cells, such as dermal dendrocytes, macrophages, and certain stromal cells. This helps diagnose disorders linked to FXIII deficiency (congenital or acquired) and characterize fibrotic or inflammatory conditions, including scleroderma, keloids, and chronic wounds. In tumors, FXIIIa-positive stromal cells may indicate specific microenvironmental interactions.
Research applications include studying FXIIIa's role in vascular biology, inflammation, and cancer progression. Deficiencies in FXIII predispose individuals to bleeding, while overexpression correlates with fibrosis and thrombosis. FXIIIa antibodies thus serve as vital reagents for both clinical diagnostics and mechanistic studies of thrombotic, inflammatory, and fibroproliferative diseases.
