Factor XIII or fibrin stabilizing factor is a zymogen found in blood of humans and some other animals. It is activated by thrombin to factor XIIIa. Factor XIIIa is an enzyme of the blood coagulation system that crosslinks fibrin. Deficiency of XIII worsens clot stability and increases bleeding tendency. Human … See more Within blood, thrombins cleave fibrinogens to fibrins during coagulation and a fibrin-based blood clot forms.
