eBook: Antibody–Drug Conjugates —
A New Generation of Approaches Is Changing the Game

by , , and

Combining large proteins with linkers and cytotoxins, antibody–drug conjugates (ADCs) may be the most complex drug molecules in development today. Despite early promise and product approvals, a number of technical concerns arose during product and process development. Characterizing and ensuring consistency in the number of small molecules that attach to the antibody — as well as ensuring their proper attachment and biophysics — all present significant challenges to ADC developers. Solving early problems associated with product quality has introduced a…

AAV Downstream Process and Product Characterization: Integrating Advanced Purification and Analytical Tools into the Workflow

by , and

The optimization of the downstream process for Adeno-associated virus (AAV) production with consistent quality depends on the ability to characterize critical quality attributes affecting potency, purity and safety of the final product. As the gene therapy field continues to push products through the clinical pipeline, an increasing need for efficient purification and analytical tools has become evident. In addition, the regulatory space has expanded in parallel to the use of AAV, driving the demand for simple and efficient assays to…

Purity By Design

by , , , and

Astrea Bioseparations has a well-established modular program to support customer projects from small to large scales with ligands, adsorbents, and chromatography columns that design purity into each process. Demand for increased productivity in biopharmaceutical manufacturing has placed new pressure on downstream purification operations. For recombinant proteins and monoclonal antibodies (MAbs), such pressure stems from significant gains in upstream productivity, particularly from high titers produced using increasingly efficient cell-culture systems. For viral vectors used in gene and gene-modified cell therapies and…

High-Yield Production of rAd26-S for Sputnik V Vaccine Component I: An Optimized Process in a Scalable Shaken Bioreactor

by , , , , , , , and

The recent outbreak of the severe acute respiratory syndrome coronavirus (SARS-CoV-2) led to the development of different vaccine approaches worldwide to prevent the coronavirus disease 2019. The first registered vaccine on the market was the Sputnik V product based on two recombinant adenoviral vectors (Ad5 and Ad26). The product has received approval in 70 countries by several national and regional regulatory authorities, meanwhile. Though the availability of SARS-CoV-2 vaccines in most developed countries is not an issue any longer, other…

Gain Control of Culture Conditions: Technology for Sustained Delivery of Recombinant Proteins

by and

Growth factors, added at the precise time and concentration to in vitro cultures are essential to control cell proliferation and differentiation. When added to a culture vessel, however, the concentrations of these signaling proteins rapidly decline, altering both levels of individual growth factors and the ratio of factors for cell signaling. When growth factors are replenished by exchanging the medium, concentrations peak, resulting in an ebb and flow of growth factor levels resulting in mixed signaling that can lead the…
