Is Helixate® FS a recombinant product?
A. Helixate® FS is a recombinant factor VIII product that is manufactured using a baby hamster kidney (BHK) cell line. In the purification and formulation steps, the human albumin used as a factor stabilizer in original Helixate® Antihemophilic Factor (Recombinant) has been replaced with sucrose in Helixate® FS; however, a highly purified plasma protein is still used in the fermentation medium.
