The recombinant era for haemophilia began in the early 1980s with the cloning and subsequent expression of functional proteins for both factors VIII and IX. Efficient production of recombinant clotting factors in mammalian cell culture systems required overcoming significant challenges due to the complex post-translational modifications that were integral to their pro-coagulant function. The qu...

This review focuses on the use of recombinant porcine factor VIII (FVIII) for the treatment of bleeding episodes in patients with severe haemophilia A complicated by inhibitors and in those with acquired haemophilia A due to the onset of anti-FVIII autoantibodies. We present the main characteristics of recombinant porcine factor VIII (FVIII) and provide a summary of the published results of the...

b ackground: the prevalence of urinary tract infection (uti) is really high in the world. escherichia coli is a major agent of uti. one of the strategies for decreasing uti infections is vaccine development. as the attachment is a really important stage in colonization and infection, at- tachment inhibition has an applied strategy.  fimh protein is a major factor during bacterial colonization i...

background and objectives: brucellosis is an important health problem in developing countries and no vaccine is available for the prevention of infection in humans. because of clinically infectious diseases and their economic consequences in human and animals, designing a proper vaccine against brucella is desirable. in this study, we evaluated the immune responses induced by a designed recombi...

The bacterial endotoxin test, which uses amebocyte lysate reagents of horseshoe crab origin, is a sensitive, reproducible and simple assay to measure endotoxin concentration. To develop sustainable raw materials for lysate reagents that do not require horseshoe crabs, three recombinant protease zymogens (factor C, derived from mammalian cells; factor B; and the proclotting enzyme derived from i...

Factor IX has been expressed to high levels within a recombinant host cell and the biologically active fraction subsequently purified to homogeneity for characterization. The coding sequence for Factor IX was inserted into a mammalian cell expression vector and transfected into dihydrofolate reductase-deficient Chinese hamster ovary cells. The integrated DNA was amplified to a high copy number ...
