Fast, accurate determination of vaccine titer during influenza vaccine manufacture (Figure 1) is important in understanding process performance and correctly scaling each process step. Traditionally, single radial immunodiffusion (SRID) assays have been used as the gold standard, but they require very skilled operators to obtain reproducible results and is relatively low throughput. ELISAs have also been used to determine titer, but they have lower precision and dynamic range. Bio-Layer Interferometry (BLI) combines the high-throughput characteristics of a 96-well- plate–based ELISA assay in conjunction with higher accuracy and reproducibility derived from a simpler direct measurement of vaccine/analyte binding.

This application note describes a monoclonal antibody (MAb) purification process using the expanded MAb purification toolbox of GE Healthcare’s Life Sciences business, covering modern chromatography media (resins) for standard and challenging purification tasks. The most established approach for purifying MAbs is a three-step process, where the initial capture step using a protein A medium is followed by two polishing steps using cation- exchange (CIEX) and anion-exchange (AIEX) media (Figure 1a). However, for more challenging MAb purifications, an expanded MAb purification toolbox is beneficial. Here, a multimodal AIEX medium was used as an alternative in final polishing of a MAb with low monomer stability (Figure 1b). Using the described approach, the set criteria for the polishing steps were achieved, with a recovery of >90% over each step and an aggregate content <1% in the final product.

Pall’s patented single-pass tangential-flow filtration (TFF) technology simplifies current TFF processes (
1
). It eliminates the conventional TFF recirculation, allowing an efficient single-pass operation without mixing or foaming issues and exposes the product to low shear, which optimizes the processing of fragile and shear-sensitive molecules. The single-pass feed flow rates are lower than those of conventional TFF, minimizing the hold-up volume and maximizing product recovery. It allows for higher final concentrations because processing limitations due to minimum working volumes are optimized (

Strong anion-exchange (Q) chromatography is an industry standard for polishing purification steps of monoclonal antibody (MAb) production. It is a proven technology that removes viruses and host-cell proteins (HCP) from process feed streams in flow-through mode. NatriFlo HD-Q device adsorbers feature a hydrogel membrane, which combines high dynamic binding capacity and salt tolerance to deliver best-in-class 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 adsorbers to clear virus and HCP from partially purified (post–protein A) MAb solutions.

POROS™ XQ is a next-generation strong anion- exchange resin with a fully quaternized amine surface chemistry. It was designed to retain all the beneficial performance attributes of POROS HQ resin, such as resolution capability, flow properties, and physical stability, with the added benefits of higher capacity and salt tolerance. Those were realized by optimizing the pore structure, which drives better access of biomolecules to the surface charge, and by optimizing the amount of surface charge (the ligand density) as measured by ionic capacity. Better access to a higher amount of ionic capacity increases dynamic binding capacity (DBC) and improves salt tolerance, because the resin can withstand higher amounts of counterion and still allow effective protein binding.

Design of Experiments (DoE), also called experimental design, is a statistical approach to process development that has gained wide acceptance in the biopharmaceutical industry. DoE is used to reduce development costs by speeding up the design process and to optimize the parameters of a particular step in the manufacturing process. With its inherent ability to take into account multiple variables at once, a designed experiment is also used to minimize process variation leading to a more robust manufacturing process.

A polishing step for the purification of a monoclonal antibody (MAb) using TOYOPEARL NH2-750F was developed. In general, anion-exchange resins can be used in bind and elute (B/E) mode as well as in flow- through (FT) mode. Both options were evaluated. To increase the amount of aggregates of the test sample, a MAb was aggregated by acidic incubation and subsequently diluted to 1 g/L in loading buffer.

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 and prior to patient administration, to ensure effective patient response.
BioCision recognized cell thawing as a process that has been historically overlooked but is critical to the success of the overall process. Consequently, the company developed the ThawSTAR™ Automated Cell Thawing System – an instrument that senses the contents of each cryogenic vial and customizes a rapid thaw of the...

Ensuring optimal and maximal T-cell production is critical for adoptive immunotherapy and its continued success. The Xuri Cell Expansion System is an important component of the clinical manufacturing process. So we sought to investigate the effect of rocking rate and angle on the expansion of T cells. We used a combination of experimental data and predictive modeling and found that the rocking rate significantly influences the expansion potential of T cells with minimal contribution from the rocking angle. The results indicate that a rocking rate of 15 rocks per minute (rpm) and an angle of 6° are optimal for a 1-L bioreactor to maximize cell growth using a Xuri Cell Expansion System.
