Human Interferon Beta-1b Production in Pseudomonas fluorescens

          Interferon beta-1b is a protein in the interferon family used to treat the relapsing-remitting form of multiple sclerosis (MS). Interferon beta-1b is a natural human protein (molecular weight ~18,500 Da) that is produced in the body in response to viral infection and has antiviral activity. It has been shown to slow the advance of MS and reduce the frequency of attacks. It is believed that interferon-beta achieves this effect on MS progress via its anti-inflammatory…

Preserving Chromatographic Selectivity While Improving Your Process Purification

          Chromatographic resins for a new purification process are initially selected based on prior experience and knowledge of the feedstock and the target compound. As the process scales larger, and hopefully through therapeutic commercialization, developers seek opportunities to maximize throughput, remove impurities, and reduce cost. Responding to the dramatic increase in batch titers over the past decade, products such as the Toyopearl GigaCap series of resins (first introduced in 2007) were developed to meet the titer…

Optimum Prefilter Selection and Filter Train Sizing for Media Filtration

          The use of 0.1-µm rated sterilizing grade filters has been increasing in cell culture media filtration due to mycoplasma contamination concerns. Currently, no standards exist for conducting mycoplasma retention testing on these 0.1-µm labeled filters. A task force has been established at PDA to publish a technical report to standardize testing. Until such guidelines are published, conducting side-by-side tests under identical conditions is the only fair way to compare different 0.1-µm rated filters. Sartorius Stedim…

Outsourcing Your Advanced Biologics GMP Manufacturing

Biotech companies appreciate the challenges involved in raising sufficient investment to support their drug development pipelines. In today’s economic conditions, it is even more critical that burn rates are minimised along with risks to achieving major product development and clinical milestones. Having reached the preclinical stage, the strategic decision whether to build in-house capability or outsource biopharmaceutical manufacturing will have been made. Limitations with investment is the main factor that will direct most companies to seek the services of a…
