This property is due to a contaminant denominated Prothrombin Activating Derivative-B, identified as factor XII. The fibrinolytic fraction accompanies prothrombin throughout the purification procedure and may be separated by chromatography on DEAE cellulose. Full Text References References 1 Celander D.
