Continuous Harvesting Of Extra-Cellular Proteins From Mammalian Cell Cultures Utilizing Small-Scale Perfusion
The use of a small-scale cell culture system not only maximizes the production of valuable protein but also avoids the high capital cost associated with system scale-up. Continuous harvesting can provide significant improvements in protein yields when compared to those of typical batch operations.

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.

Biomanufacturing Flexibility
This white paper from BIO-G looks at how to create flexible, agile manufacturing facilities to respond to the current glut of biomanufacturing capacity and industry consolidation. Future proofing these facilities for higher titers and multiple product lines is also explored.

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.

Sartopure PP2 Cartridges were optimized for the wide range of prefiltration.
Mixed-mode chromatography resin is a top tier selection for the manipulation, purification and handling of molecules; providing an unmatched level of separation properties and resolution. The combination of cation exchange resin and metal affinity resin properties, allows multimodal chromatography to provide an access route for biomolecules to separate and the use of alternative chromatographic methods make these biomolecules seem homogenous.
Macro-Prep hydrophobic interaction chromatography (HIC) media are methacrylate-based, 50 µm beads used for protein, polypeptide, enzyme, and nucleic acid purification.

Bioprocess With The Bozenhardts is back, with a fresh episode packed with advice from Herman and Erich on the selection of filling systems for biopharmas. Listen in as the Bozenhardts give us an update on the process, logistics, and administration trends that are informing filling system decisions today, and offer direction on making choices that will prepare you for the fast-advancing therapies of tomorrow.
Bio-Rad now offers two very high capacity ion exchangers: Nuvia S, which can be used for capture and/or intermediate polishing; and Nuvia Q, which can be used for intermediate and/or final polishing.
