Factor XII (FXII) is a protease that is mainly produced in the liver and circulates in plasma as a single chain zymogen. Following contact with negatively charged surfaces, FXII is converted into the two-chain active form, FXIIa. FXIIa initiates the intrinsic blood coagulation pathway via activation of factor XI The factor XII (FXII)–driven contact system and its activator polyphosphate (polyP) can serve as a paradigm that connects coagulation and inflammation. Here, we Factor XIII, an enzyme that cross-links fibrin, belongs to the blood coagulation system. [ 1, 2] Screening for factor XIII, also known as fibrin-stabilizing First Online: 14 August Accesses. 9 Citations. Part of the Methods in Molecular Biology book series (MIMB,volume ) Abstract. Blood coagulation factor XIII (FXIII) is essential for maintaining hemostasis. The absence of FXIII results in severe bleeding diathesis, which without prophylaxis frequently leads to Coagulation factor XIII (FXIII) is a transglutaminase with a well defined role in the final stages of blood coagulation. Active FXIII (FXIIIa) catalyzes the formation of ϵ- (γ-glutamyl)lysine isopeptide bonds between specific Gln and Lys residues Factor XIII assay. Coagulation factor XIII is a transglutaminase that catalyzes covalent cross-linking bonds between the α and γ chains of fibrin polymer. Cross-linking Factor XIIIa is an enzyme of the blood coagulation system that crosslinks fibrin. Deficiency of XIII worsens clot stability and increases bleeding tendency. [1] Human XIII is a heterotetramer. It consists of 2 enzymatic A peptides and 2 non-enzymatic B peptides. XIIIa is a dimer of activated A peptides. [1] Function
