Improving DNA Removal from Bioprocess Purification Processes
Many new biological drug products produced using recombinant DNA technology, such as monoclonal antibodies, are produced in cell culture. Because therapeutic proteins such as monoclonal antibodies are produced in cell culture, impurities can result from the host cells, or cell substrates. By 3M Purification Inc.

The Challenge of Measuring Total Organic Carbon In Modern Pharmaceutical Water Systems
Total Organic Carbon (TOC) is one of the quality attributes defined in the European and USA pharmacopoeias for pharmaceutical waters. Modern water treatment systems can deliver such high purity water that TOC levels can be consistently close to zero and very difficult to measure with any accuracy. This paper discusses some of the challenges when using TOC analysers to demonstrate pharmacopoeial TOC level compliance for modern water systems in the light of the ICH Q2 document from the International Conference on Harmonisation.

Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media
Monoclonal antibodies (mAbs) remain a predominant class of therapeutic protein products on the market because of their wide range of applications in disease treatment and diagnosis. Over the years, upstream technology advancements have helped improve the titer of target antibodies, from merely 1 g/L two decades ago to 10–13 g/L in fed-batch processes and up to 25 g/L in perfusion cultures today (Gronemeyer et al. 2014).
