Crude Sample Analysis in Process Development: Time and Cost Savings

This overview highlights a few examples from drug discovery and process development where the Octet® system demonstrated a significant reduction in the analysis time over ELISA and HPLC by eliminating the need for purification, while still achieving high accuracy and precision. The total assay times were dramatically reduced with fewer assay steps and less labor time involved. The easy and versatile, fully integrated Octet® assay has additional advantages over other label-free technologies like SPR, where sample washing steps are required.…

Expanding Applications in Downstream Biologics Characterization: Stability, Formulations and Aggregation Studies using Octet®

Structure is an important characteristic for protein activity and function. Structural alterations due to protein mis-folding, denaturation or unfavorable conditions can lead to the formation of aggregate species that can affect the efficacy and safety of biologic drug candidates. While many biophysical analytical tools are well suited for detecting these aggregates, few offer a combination of structural and functions assessment in the same system. Sartorius’ Octet® platform is an easy-to-use analytical tool that can detect the presence of aggregated species…

Transfection Reagents for Cell and Gene Therapy

Polysciences offers high-quality, R&D and cGMP grades of transfection reagents for the smooth transition from process development through clinical trials and commercial manufacturing of viral vectors/protein. Polysciences R&D grade PEI MAX has been used by academic and industry customers for over a decade and is one of the most cited transfected reagents. A few years ago Polysciences launched an easy to use liquid version of PEI MAX which is called Transporter 5 focusing on increased customer convenience. Both PEI MAX…

FAQs: Challenging host cell protein assays for improved risk mitigation

Host cell proteins (HCP) are critical to quality control in biologics development. If left unremoved, they can cause immunogenic responses and reduce drug efficacy. In our last webinar we shared Cytiva’s strategy for designing a comprehensive HCP risk mitigation strategy. We discussed how to challenge your assays early to ensure accurate measurements, build confidence, and reduce the risk of unexpected HCP levels. Our HCP experts highlighted and responded to the most common questions raised around host cell protein assays. Want…

Fragment-Based Screening in Drug Discovery: How to Improve Hit Rates & Deliver Higher-Value Targets

Learn about the basics of fragment-based drug discovery (FBDD), one of the most valuable approaches to small molecule screening and now even more widely used today by pharma companies than high-throughput screening (HTS) HTS’s main limitations — low success rates for more challenging targets, high level of false positives, and the size of the compound libraries — are propelling the use of FBDD. This change is also driven by the rise in the number of explorative targets, which demands not…

Single-Use Systems: Globalizing Best Practices and Technology Specifications

The challenges of multi-national bioprocessing operations are numerous. They include finding highly skilled experts for each site, lack of expertise with single-use systems, contamination risks and redundant efforts and resources—all of which can lead to higher costs. But these challenges also present opportunities for increasing speed to market, eliminating redundant work and overall cost savings. This white paper details the best practices used in global drug manufacturing. The key is global coordination. Best practices and specifications need to be identified…

Manufacturing Pluripotent Cell Therapeutics

Here we review strategies for gaining Food and Drug Administration (FDA) approval of allogeneic, pluripotent cell therapies. The crux of the discussion is that when developing a cell therapeutic, it is critical to look as much as a decade ahead to when FDA approval will be sought to commercialize the product through a biologics license application (BLA). While this discussion focuses on FDA approval of cell therapies, it is important to acknowledge the vast number of cell therapy clinical efforts…
