Immunogen
Factor XIII antibody was raised in sheep using purified human factor XIII as the immunogen.
Factor XIII is a transglutaminase that circulates in the plasma as a heterotetramer of two catalytic A subunits and two carrier B subunits. When thrombin has converted fibrinogen to fibrin, the latter forms a proteinaceous network in which every E-unit is crosslinked to only one D-unit. Factor XIII is activated by thrombin into factor XIIIa, its activation into Factor XIIIa requires calcium as a cofactor.
