Factor 8 and Factor 9 Deficient Plasmas

Factor-8 and Factor-9 Deficient Plasmas

Helena’s high-quality factor deficient plasmas are trusted worldwide by pharmaceutical and government customers, offering a reliable method for the quality control of haemophilia treatment products.

  • Congenitally deficient plasmas ensure presence of naturally associated proteins (for example Von Willebrand Factor)
  • Provides more accurate factor deficiency clotting time
  • Residual factor activity of less than 1%
  • Available guaranteed HiV and Hepatitis-negative
  • Long-term shelf life and stability

Factor VIII and Factor IX Deficient Plasmas are widely used for the quality control of Haemophilia A and Haemophilia B treatment products. Our congenital plasmas are sourced from naturally-deficient human donors and do not suffer from the removal of other proteins which can occur with immunodepleted products.

Helena Biosciences offer a full range of Factor Deficient Plasmas in both congenital and immunodepleted formats, and our plasmas are available as guaranteed HIV and Hepatitis-negative.
