Downstream processing is increasingly seen to be a capacity constraint for many biopharmaceutical manufacturing organizations. In our current study, nearly 75% of respondents reported that their facilities were experiencing some degree of capacity bottlenecks as a result of downstream processing. In comparison, 63.8% responded the same in the previous year. As the biopharmaceutical industry increases its focus on cost containment, product pricing, and healthcare reform, critical manufacturing operations have been pushed to center stage. Over the past few years, downstream processing, which includes complex operations such as filtration of final products and chromatography operations has become increasingly challenging, from budgetary and operational perspectives. As upstream operations continue to improve, the ability of current downstream facilities to handle the additional load has led to strains and constrictions. The industry is open to new solutions although few alternatives to current processes have been presented. A number of promising innovative technologies are on the horizon, but it will be a few years or more before they debut in clinical or commercial production operations….


With the ­development of bacterial fermen­tation and ­mammalian cell culture as the sources for new recombinant products came a standardization of raw feed stocks. Therefore, manufacturers came to share the same types of problems. This standardization allowed a more systematic approach to process development divided into upstream (bacterial and yeast fermentation or mammalian cell culture) and downstream processing activities…


The last 30 years have seen rapid and dramatic developments in recombinant DNA technology and the related biological sciences. In 1972, Paul Berg’s group used restriction enzymes to cut DNA in half and then used ligases to stick the pieces of the DNA back together. By doing this, they produced the first recombinant DNA. Within a year, the first genetically engineered bacterium existed. A little more than ten years later, recombinant human insulin was approved for diabetic patients and became the first recombinant healthcare product. Before the end of the 1980s, the first gene therapy trial had occurred. Today, a large number of recombinant proteins are used as marketed drugs and even more are in clinical trials targeting a wide range of diseases…
