Prepared from fresh frozen
human plasma. This protein purity is determined by SDS-PAGE and
shows no reduction upon incubation with 2-mercaptoethanol. Activity is determined via clotting assay. Human Factor IX, activated by either the
Contact or Tissue Factor Pathway, is responsible for the activation
of Factor X to Xa.
