Activated clotting factors in factor IX concentrates.
The precise quantitation of activated factors in human factor IX concentrates has been accomplished with the use of recently developed, specific assays for factors IXa, Xa, and thrombin. The assay for factor IXa, which measures the initial rate of 3H-factor-X activation, was shown to be specific for factor IXa in the concentrates. Activated factor IX concentrates contained 1.0-2.3 microgram/ml ...
متن کاملThe History of Clotting Factor Concentrates Pharmacokinetics
Clotting factor concentrates (CFCs) underwent tremendous modifications during the last forty years. Plasma-derived concentrates made the replacement therapy feasible not only in the hospital but also at patients' home by on-demand or prophylactic regimen. Virucidal methods, implemented soon after hepatitis and AIDS outbreak, and purification by Mabs made the plasma-derived concentrates safer an...
متن کاملHepatitis C viral RNA in clotting factor concentrates and the development of hepatitis in recipients.
The polymerase chain reaction (PCR) was used to detect hepatitis C (HCV) viral sequences (HCV-RNA) in clotting factor concentrates that had been stored at 4 degrees C for 1 to 16 years. A total of 43 concentrates were tested, comprising 31 batches of factor VIII, 6 of factor IX, 2 of antithrombin III, 3 of FEIBA, and 1 of factor VII. HCV-RNA was detected in 13 of the 43 batches (30.2%). Concent...
متن کاملRecombinant clotting factor VIII concentrates: Heterogeneity and high-purity evaluation.
Factor VIII is an important glycoprotein involved in hemostasis. Insertion of expression vectors containing either the full-length cDNA sequence of human factor VIII (FLrFVIII) or B-domain deleted (BDDrFVIII) into mammalian cell lines results in the production of recombinant factor VIII (rFVIII) for therapeutic usage. Three commercially available rFVIII concentrates (Advate, Helixate NexGen and...
متن کاملPlatelet Factor 3 Based-clotting Time Assay as a Quality Marker for Long-term Storage of Platelet Concentrates
Background: Platelets rapidly lose their qualities usually after 5 day of storage. Different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. The purpose of this study was to demonstrate if platelet factor 3 (PF3) assay could be an indicator of storage lesion and provide ...
