FIX Imm. Depleted PlasmaCRYOcheck Factor IX Deficient Plasma is recommended for use as a deficient substrate in clot-based factor IX assays using the activated partial thromboplastin time (APTT). Deficiencies in coagulation factors may have congenital or acquired etiologies and can compromise in vivo hemostasis. Factor IX (antihemophilic B factor) is a single-chained glycoprotein with a molecular weight of 55,000-57,000 Da and is necessary for intrinsic coagulation. Plasma samples deficient in coagulation factor IX exhibit a prolonged APTT. Factor IX deficiency (hemophilia B) is commonly diagnosed through the use of a modified APTT assay. When a patient sample is mixed with factor IX deficient plasma, the degree of correction of the APTT is proportional to the level of factor IX in the patient plasma. |
