Scale-Down Optimization to Scale Up Success

As immune cell therapy advances to address new indications, the need for rapid development of robust manufacturing processes becomes increasingly important. Early process optimization sets the stage for clinical and commercial manufacturing and plays a foundational role in decreasing time to market and lowering COGS. This application note describes the streamlining of T-cell expansion optimization using a DOE-based approach in a semi-automated, controlled multi-parallel setup of the Sartorius T-Cell Exploration and Characterization Solution.

MAb Quantitation: Protein A HPLC vs. Protein A Bio-Layer Interferometry

Rapid, accurate and cost-effective quantitation of monoclonal antibodies (MAbs) is essential for bioprocessing. High Pressure Liquid Chromatography (HPLC) and the Octet® are some of the commonly used techniques for MAbs titer determination. To ensure MAbs purification column efficiency, the dynamic binding capacity (DBC) of Protein A for Mab can be determined by loading feedstock onto the column until binding sites for the MAb become saturated and MAb begins to break through. An assessment of the relative merits of Protein A…

The Viscosity Reduction Platform: Viscosity-Reducing Excipients for Protein Formulation

Protein viscosity is one of the major obstacles in preparing highly concentrated protein formulations suitable for subcutaneous (subQ) injection. Highly viscous protein solutions would require a significant force to be applied to the syringe for injection. As a result, the patient could experience a considerable amount of pain. In many cases, injectability would not be possible. When characterizing protein viscosity behavior, one can differentiate two different concentration regimes. At very low concentrations below about 75 mg/mL, proteins are rarely viscous.…

Accelerating Discoveries for Viral Biology and Host Immunity with Advanced Cell Analysis Solutions

This whitepaper summaries recently published studies that incorporated the Incucyte® Live-Cell analysis platform and iQue® 3 Advanced High-Throughput Flow Cytometry. These state-of-the-art technologies were used to simplify workflows and provide rapid analysis solutions and enhanced throughput, aiding the discovery of new insights on the host-pathogen life cycle throughout the course of infection. Post-infection, these platforms were leveraged to monitor exposure, assess immune protection, and accelerate the development of anti-viral small molecules, neutralizing antibodies, and vaccines. The Incucyte® platform offers automated…

Using Bio-Layer Interferometry for A Fast and High Precision Influenza Vaccine Potency Assay

A fast and accurate determination of vaccine titer during manufacturing is important in understanding vaccine development process performance, and for correctly scaling each process step. The Single Radial Immunodiffusion (SRID) technique has been the most commonly used technique for vaccine titer determination. However, SRID is time consuming and generally exhibits poor precision. An alternative assay that can speed up the analysis process and provide accurate and precise potency data on different vaccine strains is therefore desirable. The Octet® platform’s Bio-Layer…

Assessing Your AAV Capsid Content for Product Quality? Get the Confidence You Need with an Automated CE Platform

Looking for a hassle-free and rapid analytical method to detect full, partially filled, and empty Adeno-associated virus (AAV) capsids for your gene therapy development? Viral capsid content can impact gene therapy product efficacy and is therefore considered a Critical Quality Attribute (CQA) that must be properly evaluated during the development and manufacturing of AAVs. Traditional analytical tools such as transmission electron microscopy (TEM), analytical ultracentrifugation (AUC), and ion-exchange chromatography (IEX) can be used to characterize capsid content but are complex…

Cell Line Development: Accelerating Process Optimization by Combining Ambr® 15 Cell Culture with Octet® Titer Measurements

Cell line development (CLD) involves the screening of thousands of clones to find those that are stable, produce high yields of the bioproduct and exhibit desired critical quality attributes (CQAs). Typically screening and process optimization activities will be carried out at the small scale in bioreactor cultures to ensure that results translate up to larger bioreactor scales. Performance data is primarily based on cell growth, cell viability, metabolite analysis and product titer, and assessed over the entire culture process duration.…

Enhancement of Tablet Coating Using an Innovative Functional Excipient

During formulation of solid dosage forms, film coating is used to improve the appearance and stability of tablets, make them easier to swallow, mask the taste, modify or sustain release, protect the drug from the harsh gastric environment, protect from moisture and/or oxidation and, as a result, to improve the stability and overall therapeutic effect of the final drug product. Depending on the individual needs, a polymer with appropriate properties is chosen during formulation development to serve as film-coating matrix.…

Cytiva Strategy for Host Cell Protein Control

A critical aspect of therapeutic development and manufacture is host cell protein (HCP) detection, quantitation, and removal from drug substances, to ensure efficacy and prevent immunogenicity. It is important to mitigate risk by challenging your assay for each new molecule and selecting the most suitable kit. Cytiva offers a range of solutions to support scientists and developers in creating an effective strategy for HCP control. Read more about our strategy for HCP control.
