Continuous and semi-continuous cell culture for production of blood clotting factors

Journal of Biotechnology

Abstract

Recombinant clotting factors are important biotherapeutics that Pfizer has produced and marketed for over fifteen years. Owing to the complexity of the structure and function of these blood factors, it can be challenging to achieve the required product quality and manufacturing productivity. The article highlights the semi-continuous and continuous cell culture processes employed by Pfizer for the production of BeneFIX and ReFacto AF. The benefits of such processes, the challenges of maintaining an aseptic production culture for extended periods, and batch definition are discussed in this article.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
