In this study, anion-exchange chromatography was used to purify factor VII
and factor IX from prothrombin complex (PPSB), which contains coagulation
factors II, VII, IX and X. For this purpose, DEAE-Sepharose CL-6B gel , Pharmacia
column XK-26 , high flow rate and two stepwise gradients with phosphate citrate
buffer were used. The yield of the two lyophylized products, factor VII and factor
IX concentrates, was 61 % and 75%, respectively. Specific activity of factor VII
increased from 0.16 to 3.06 (purification-fold= 19.1) and specific activity of factor
IX increased from 12 to 4.9 (purification-fold= 4.1). Results of electrophoresis
on agarose gel-as well as immunoelectrophoresis-indicated higher purity of
factor VII and factor IX compared to PPSB. Thrombogenicity of the two products
were within the normal range defined for PPSB. In order to improve viral safety,
solvent-detergent treatment was performed prior to further purification. Factor
VII concentrate is used for patients with factor VII deficiency and also for hemophilia
patients with inhibitors. Factor IX concentrate is used for treatment of hemophilia
B patients.
