A new and simplified anion exchange chromatographic process for the purification of both live and inactivated cell grown H1N1 influenza viruses was established with a recently developed anion exchanger. The resin is designed with an optimized surface extender and pore size for superior accessibility and large biomolecule binding capacity, aiming to overcome common drawbacks of existing ion exchangers for virus purification.

Understanding how T cells respond to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical in developing long-term therapeutic approaches, as well as helping inform strategies for future pandemics. Learn how one team at the La Jolla Institute for Immunology in San Diego, California, has been using novel T-cell activation assays to understand how our immune system responds to SARS-CoV-2.

Inadequate quality control assays shouldn’t limit cell and gene therapy applications. Instead, quantifying the potency of cell and gene therapies is essential for successful therapeutics. In this article, we describe multiple leading potency assays developed using Droplet Digital PCR (ddPCR) technology, including an assay that quantifies transgene integration and expression in one step.

Through the CFX Duet Real-Time PCR System, our newest generation of quantitative PCR (qPCR) instrumentation, this technology is now even more accessible for molecular biologists and other professionals doing essential qPCR. With CFX Maestro Software, you can perform duplex detection, gene expression, and genotyping, all without paying for additional optics you don’t need. Check out our video tour of the new CFX Duet System.

Gene editing is only useful if it’s successful. Read how scientists are leveraging the unparalleled accuracy and specificity of ddPCR technology to optimize quality control in gene editing projects, including HIV detection and CAR-T cell generation.

RNA-Seq library preparation is a manually intensive, time-consuming process prone to bias from the multiple enzymes required. So, how can you trust your sequencing results? Bio-Rad is revolutionizing RNA-Seq library prep with the SEQuoia Express Stranded RNA Library Prep Kit – a three-hour, three-tube solution eliminating the need for multiple enzymes and reducing both the number of pipetting steps and protocol time. The key is an engineered, proprietary retrotransposon called SEQzyme. With this serial template jumping, or continuous synthesis, reaction you can obtain an unbiased, stranded RNA-Seq library constructed to accurately represent both messenger and non-coding RNA from your sample.

Bio-Plex Pro SARS-CoV-2 Neutralization Antibody Assays provide reliably measure neutralizing antibodies in less than 3 hours. Watch our webinar to learn more.

Monoclonal antibody (mAb) purification methods often involve the use of resin-based chromatography. In this video, we compare a three-step mAb purification workflow, which uses Nuvia Ion Exchange Resins post–Protein A capture, to a two-step purification workflow, which includes a Protein A capture step followed by a mixed-mode chromatography step using Nuvia aPrime 4A Resin, a hydrophobic anion exchange resin. We present an additional two-step purification approach using Protein A resin followed by a calcium affinity cation exchange media, CHT Ceramic Hydroxyapatite XT Media. The results of both studies demonstrate that a high purity product can be attained using one fewer unit operation than traditional workflows.

Cell and gene therapies have seen record growth due to their potential to address the underlying causes of genetic and acquired diseases. Non-viral delivery methods are increasing in popularity due to their safety, cost-effectiveness, reduction in manufacturing time, and flexibility compared to viral vector delivery methods. Electroporation is a simple, broadly applicable method capable of delivering molecules to a wide range of cell types for either cell or gene therapy. This article outlines the top advantages of using electroporation in cell and gene therapy and why it might be a good approach for your own research group.
