Abstract

Biopharmaceuticals are mostly protein-derived medical drugs play vital roles in the human body catalyzing sequence of biochemical reactions. These biologics, which include therapeutic proteins, monoclonal antibodies (MAbs), vaccines, hormones, and fusion proteins, are used in the treatment, diagnosis and prevention of specific diseases such as cancer, multiple sclerosis, rheumatoid arthritis, diabetes, and a variety of cardiovascular diseases [1-3]. They are large molecular weight compounds with complex 3D structures mimicking molecules found in human bodies. Their production by living cells makes them different from classical small molecular weight chemical drugs (e.g., antibiotics) and in general, protein drug production by living cells is generally difficult [3]. With the advent of recombinant DNA technology, the post genomic era is seeing a massive increase in valuable protein products entering the clinical trials to manage disease with high specificity [4]. The global market for recombinant bio-pharmaceuticals has been growing rapidly from 30 products with a market value of USD $50-60 billion in 2004 to more than 151 unique products approved by the FDA by 2012 valued at USD $138 billion and is expected to surpass $320 billion by 2020.
