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.

Guidelines For Proper Filtration And Delivery Of Samples To On-Line Process Analyzers
Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.

Avoiding Drug Shortages With Microbial Detection
Over the past year, critical drug shortages used to treat a host of life-threatening illnesses have been making headlines. Microbial contamination has been cited as a major contributor to the shortage, yet the prevailing practices to ensure the safety of drugs have been slow to change. In most cases, quality assurance practices safeguarding the drug making environment continue to rely on periodic air and a culturing method from a prior century.
