Increased Monoclonal Antibody Resolution with TSKgel® UP-SW3000 Columns

The antibody therapeutics market is enjoying high growth rates, the major areas of therapeutic application being cancer and immune/inflammation-related disorders including arthritis and multiple sclerosis. In 2013, six of the top ten best-selling global drug brands were monoclonal antibodies (mAbs) and more than 400 mAbs were in clinical trials. The characterization of these complex biomolecules is a major challenge in process monitoring and quality control. The main product characteristics to be monitored are aggregate and fragment content, glycosylation pattern and…

Characterization of Subvisible Particles in Vaccine Development

Vaccine manufacturers want meaningful information that can be linked to process knowledge to increase product quality and eliminate patient safety issues. New requirements from the United States Pharmacopeial Convention (USP) and the U.S. Food and Drug Administration (FDA) put pressure for root cause analysis to understand impact on changes during process and product development. The new demands involve not only size and distribution but deeper characterization that involves morphology and composition studies as part of particle characterization. Nanoparticles like virus,…

How Molded Manifold Assemblies Prevent Leaks & Costly Consequences

Molded tubing manifolds have roles to perform over and above being a transport vehicle for liquids. The assemblies must maintain leak-proof flow. They need to meet sterility requirements and help limit the need for cleaning and associated validations. They also must be cost effective, simple to use and efficient. When compared with hand-assembled tubing sets, the advantages of molded tubing manifold assemblies are clear. Tubing sets made from multiple components present a risk of leaks at every juncture. With barbed…

Development of a Novel Cold-Chain Tubing, FP-FLEX™, and Single-Use Freezing Bag: For Working Cell Banks Enabling Closed-System Processing to Temperatures As Low As –196 °C

Working cell banks (WCBs) are commonly applied to initiate cell culture manufacturing campaigns to produce therapeutic proteins. Those campaigns typically begin with the inoculation of cells previously cryopreserved in vials. Although vials are typically used to establish WCBs and initiate manufacturing campaigns, they are not optimal for the growing demands of commercial production.

ThawSTAR™ Automated Cell-Thawing System: Breakthrough Adaptive Sensing Technology for Reproducible, Standardized Cell Thawing

Advances in cryopreservation techniques have been crucial for the substantial progress achieved in many fields, including cell biology research, drug discovery, bio-banking, and assisted reproduction. While cryopreservation techniques have markedly improved, downstream cell thawing techniques have thus far been neglected, even though proper thawing of cryopreserved materials is essential for optimal cell viability. The success of high-promise fields such as cellular therapy and regenerative medicine require reproducible and standardized handling of the therapeutic cells, which includes thawing both during manufacturing…

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…

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…

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…
