<prompt> Which clotting factor is required for stabilization of fibrin clot?XIIIaVIIIIXV  <response>: The fibrin is initially a loose mesh of interlacing strands. It is conveed by the formation of covalent cross-linkages to a dense, tight aggregate stabilization. This latter reaction is catalyzed by activated factor XIII ie XIIIaVIII - Antihemophilic factor AHF, antihemophilic factor A, antihemophilic globulin AHGIX - Plasma thromboplastin component PTC, Christmas factor, antihemophilic factor BV - Proaccelerin, labile factor, accelerator globulinRef: Ganongs Review of Medical Physiology Twenty-Third Edition Page No:532
