Webinar: Best Practices, Strategies & Utilization of Novel Biological Responses for Robust Cell-Based Potency Assays
Transcriptional activity within a cell can be used to evaluate cell response to a ligand or promoter activity within a transgene or plasmid within a cell. Catalent has developed a relative potency bioassay using real-time quantitative reverse transcription (RT-qPCR) in a duplex format to assess relative transcription activity in cells treated with ligands or transgenic vectors. The assay utilizes two fluorescent dyes with minimally overlapping emission spectra that allow real-time monitoring of the gene expression of both target and normalizer genes. Notably, the assay simplifies the process by eliminating the need for mRNA purification, enabling more efficient and accurate analysis. Normalizing the qPCR cycle thresholds (CT) of the target transcript to the reference transcript allows the response curve to be generated and compared to a reference standard. The generation of a four-parameter fit curve analysis from raw qPCR cycle threshold data allows for the comparison of relative potency and assessment of suitability based on curve parallelism. Catalent has successfully implemented this assay platform to develop a reliable, accurate, and specific bioassay. It stands out for its linear response and reproducibility, making it a valuable tool for evaluating the relative potency of various test substances. Join us to explore how these robust cell-based potency assays can enhance your research and provide critical data on drug product potency.
Biophysical and Aggregate Characterization for the Development of Biologics
June 10th 2025This eBook explores how advanced particle analysis technologies are revolutionizing biologic drug development. It highlights the importance of accurately identifying and characterizing subvisible particles to ensure drug safety, stability, and regulatory compliance. Techniques like Backgrounded Membrane Imaging (BMI) and Fluorescence Membrane Microscopy (FMM) are often used for their capabilities in detecting protein aggregates and degraded excipients such as polysorbates. Case studies and experimental results demonstrate how these tools provide high-throughput, low-volume analysis that enhances decision-making in formulation screening and manufacturing.
The Role of On-Demand Manufacturing and Derisking in Accelerating Early Clinical Trial Success
June 4th 2025Small pharmaceutical companies are constantly seeking innovative solutions to streamline early clinical trials. Adaptive clinical trials offer important benefits to sponsors and patients, both from a commercial and ethical standpoint. These trials offer flexibility and efficiency, especially in the early stages, where trial protocols can be adjusted based on interim data, such as introducing new doses or modifying participant sample size. However, adjusting manufacturing demand during an adaptive trial can be complicated, and strict regulatory requirements present significant challenges. On-demand manufacturing provides a robust solution, allowing for real-time supply and demand adjustments and improved trial flexibility. This paper explores how on-demand manufacturing meets the operational needs of adaptive trials and aligns with regulatory expectations.
