≥95%. Factor IXa is prepared from highly purified factor IX by activation with factor XIa, as described by Lindquist et al. (5). The factor IXa is further purified by gel filtration, followed by immunoaffinity purification. Factor IXa is also available with the active site irreversibly blocked by the fluorescent inhibitor, Dansyl-EGRck. Purity is assessed by SDS-PAGE analysis. Activity is determined in a one-stage clotting assay.
