Biotechnology products development

The production of biologically important proteins by recombinant DNA techniques and development of modified counterparts is a very challenging field. Certain criteria of safety, quality, and efficacy are required for the development and approval of these protein products as therapeutic agents. The presence of structural variations during the different steps in the protein

In the early days of biotechnology product development, the focus was on quality issues [4] or process-related impurities.The concerns at that time were for carryover of other cellular proteins and DNA and for contamination with endotoxins, chemicals, and viruses. Of course, these concerns still exist, but methods for purification and assays for evaluation of clearance have alleviated the need for the safety assessment scientist to focus on contaminants instead they are now asked to focus on the pharmacological activity of the molecules. An ICH guidance (Q6B Specifications Test Procedures and Acceptance Criteria for Biotechnological/Biological Products) addresses the specific issues related to the manufacturing process [6], Other product-related issues such as impurities do need to be considered by the safety assessment scientist, for... 

Other equally important methods are the electrophoretic techniques, such as polyacrylamide gel electrophoresis, isoelectric focusing, Western blots, combined electrophoresis, and isoelectric focusing (two-dimensional electrophoresis). Bioactivity methods are other key methods used in biotechnology product development. These include in vivo whole animal bioassay, cell culture bioassay, immunoassay, and biochemical assay. Many references and several textbooks are available in many industrial and academic libraries to provide additional and up-to-date information.

Once we know the chemical nature of the allelopathic agents and their effects on plant growth dynamics, as well as on health and environment, we can apply genetic manipulation and biotechnology to develop toxin-resistant plants and to reduce the toxin levels frcm the donor plants. These approaches serve a dual purpose because they contribute to increased agricultural productivity and help to minimize the potential risks on health and environment. 

Additional future innovations likely to impact upon pharmaceutical biotechnology include the development of alternative product production systems, alternative methods of delivery and the development of engineered cell-based therapies, particularly stem cell therapy. As mentioned previously, protein-based biotechnology products produced to date are produced in either microbial... 

Niche CROs usually specialize in selected disease areas of clinical research, or may concentrate on market segments, such as medical devices, data management, IT functions, or a myriad of other singular service offerings. Such firms can be very valuable to early stage product development enterprises, such as biotechnology start-ups, which may be focused...
