Safety Considerations for Gas Filtration in High-Temperature and Oxygen Enrichment Applications

Gas filtration using sterilization-grade filters is a key part of the production, manufacturing and packaging process of biopharmaceuticals and other products. While it may seem a simple step, there are major safety considerations that have to be taken in to account to protect staff, equipment and facilities from hazard, particularly when working in high temperature and oxygen enrichment applications. This paper examines the safety issues involved, looks at material design considerations and introduces a ready-made solution for safe, effective, robust…

EMD Millipore Adds Protein Pegylation to Portfolio of Services for Biopharmaceutical Industry through Collaboration with celares GmbH

EMD Millipore, the Life Science business of Merck KGaA of Darmstadt, Germany, today announced a collaboration with celares GmbH to provide pegylation services to customers developing protein-based therapeutics and biosimilars. The new service offering enabled by the collaboration includes feasibility studies, process and analytical development, and scale-up from milligram to gram quantities required for pilot and subsequent commercial scale. Pegylation, the attachment of polyethylene glycol to a molecule, can significantly improve the pharmacological and physicochemical properties of peptide and protein…

The ViMix Vertical Shaker for Viscous Sample Mixing

Zinsser Analytic GmbH has developed a multi-position vertical shaker that can mix several samples in parallel using a 15 mm vertical movement at up to 1200 cycles per minute. Traditionally, samples can be mixed in many ways: magnetic stirring, orbital vortexing, horizontal shaking, rocking, overhead stirring etc. But in the main rotational mixing through vortexing is mainly used. However, with a vertical “up and down†motion, substantially higher acceleration can be achieved and hence better sample mixing. A vertical shaker…

Monoclonal Antibody Production: Viral Clearance and Host Cell Protein Reduction Using a High Capacity Single-Use Strong Anion Exchange Device

Strong anion exchange (Q) chromatography is an industry standard for polishing purification steps of mAb production. It is a proven technology which removes viruses, and host cell proteins from process feed streams in flow through mode. NatriFlo HD-Q devices adsorbers feature a hydrogel membrane which combines high dynamic binding capacity and salt tolerance to deliver best-inclass performance. This makes it possible to rapidly process large sample volumes using a small disposable device. This article examines the ability of NatriFlo HD-Q…

Monitoring Protein Unfolding and Refolding

Proteins exist in a highly ordered, folded state. This highly ordered structure of a protein is integral to the efficacy and safety of a protein-based biotherapeutic. Protein unfolding and refolding are an indicator of protein stability. As a protein begins to unfold, the hydrodynamic radii of the protein species change. Denaturation of proteins may range from slight and reversible conformational changes to a drastic loss of solubility, leading to irreversible aggregation. Monitoring the stability of the different protein conformations is…

Goodwin Biotechnology Announces the Completion of cGMP Manufacturing of an IgM Monoclonal Antibody and IgM : Ligand Conjugate for Q Therapeutics

Goodwin Biotechnology, Inc., a biological Contract Development and Manufacturing Organization (CDMO) that specializes in bioprocess development and GMP manufacturing of biopharmaceuticals utilizing Mammalian Cell Culture expression systems and Bioconjugation technologies, has partnered with Q Therapeutics, Inc., a clinical-stage developer of novel cellular therapies for central nervous system (CNS) diseases to provide GMP antibodies for manufacture of clinical trial materials. To do so, Goodwin Biotechnology completed Process Development, Scale Up, and cGMP manufacturing of an IgM antibody and an IgM: Ligand…

Changing Column Packing from an Art into a Science

Chromatography is often the most critical step in biopharmaceutical downstream processing because of its role as the engine for separating impurities from target biologics. The most demanding operation in production scale chromatography is typically packing the column in a way that ensures first time success and a validation result which meets the batch record standards. Traditionally column packing has been the responsibility of a few specialist operators and has been regarded almost as an art by most observers. When the…

Lonza Announces Additional Long-Term Agreement with Alexion

Lonza Group Ltd today announced the signing of a new long-term product supply agreement with Alexion. Under the agreement Lonza will construct and launch a new suite dedicated to Alexion manufacturing. Lonza will own and operate the suite as part of its Portsmouth, NH (USA) site. This contract is an expansion of an existing manufacturing agreement. This agreement will supplement existing production of Alexion products at multiple Lonza facilities. The expansion of the existing site in Portsmouth, near Boston, MA…
