cell and gene therapy

Scientists commonly use lentiviruses and adeno-associated viruses (AAVs) as viral vectors in cell and gene therapy (CGT) production. However, therapies that use these viruses must undergo strict quality control measures, including testing for replication-competent viruses (RCV), to ensure that the treatment is safe. Cell culture-based methods are currently the gold standard for RCV testing, but it can take up to 45 days for results to be returned. Droplet Digital PCR (ddPCR) kits now offer an attractive orthogonal method.

Recent advances in chimeric antigen receptor (CAR) T-cell therapy have opened exciting new avenues for the treatment of a variety of malignancies. Cytokine release syndrome (CRS), a powerful immune response to activated CAR T cells, is the primary side effect of CAR T-cell therapy, but existing CRS treatments can make CAR T-cell treatment less effective. In two recent studies, researchers used multiplexed cytokine immunoassays to better understand how CAR T-cell therapy triggers CRS and to identify strategies for early intervention in CRS development.

Anion exchange and mixed-mode chromatography offer efficient and flexible AAV purification. Learn new strategies for optimizing viral vector purification.

Lentiviral vectors (LVVs) have become the primary method of gene delivery for cells ex vivo in both academic and clinical applications. Currently, qPCR is the gold standard for functional titering of LVVs, but Droplet Digital PCR (ddPCR) offers an attractive alternative due to its inherent benefits, such as absolute quantification without the use of a standard curve and enhanced resistance to PCR inhibitors.

Chimeric antigen receptor (CAR) T cells represent the next generation of therapeutic interventions and are a major advancement in personalized disease treatment. CAR T-cell therapies utilize a patient’s own T cells to recognize and destroy cancer cells or other disease-causing cells. Find out how the ZE5 Cell Analyzer has helped overcome some of the challenges associated with development of these powerful new therapies.

In this webinar, we describe an mRNA electroporation–based workflow for CAR T cell generation. See how high viability and transfection efficiency were achieved.

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.

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.

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.
