Monoclonal Antibody Purification Platform Using High-Capacity Protein A And Mixed-Mode Chromatography
The first step in purification of an important class of therapeutic proteins, the polyclonal or monoclonal antibodies (mAbs), is their capture from plasma or tissue culture supernatants. Protein A–based media are by far the most common class of affinity products used for this purpose.

Materials Of Construction For Biopharmaceutical Water Systems
Stainless steels are uniquely qualified for bioprocessing applications not only because of their long service life, availability, and fabricability, but also because they are non-corroding, non-contaminant, can be polished to very smooth finishes, are strong and rigid, can withstand heat and chemical sterilization treatments, and are easily welded.

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.
