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.

Historically, five-year survival rates have been used to evaluate cancer therapeutic effectiveness in clinical trials. But time is critical for research — and for patients. Fortunately, there is a promising method for evaluating cancer therapeutic effectiveness that could potentially offer prognostic insights after just one year. Noninvasive liquid biopsy analysis, including analysis of circulating tumor DNA, is improving researchers’ ability to detect clinical responses more rapidly.

Carter Mitchell, PhD, is a protein problem solver. As Chief Science Officer at Kemp Proteins, he helps academic and industry researchers develop a range of protein therapeutics, diagnostics, and molecular tools in milligram to gram quantities with bioprocess scale in mind. In this interview, we discussed how Kemp Proteins ensures delivery of high-quality processes and protein-based products to their clients, even when working with difficult proteins.

Current vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have reduced the severity of the coronavirus disease 2019 (COVID-19). However, the drastic and quick evolution of the virus poses challenges to the development of durable and efficacious therapeutics for vaccine and antibody developers alike. See how the Bio-Plex Pro Human SARS-CoV-2 Neutralization Antibody Custom Assay Developer Kit speeds up the qualitative measurement of neutralizing antibodies (NAbs) against new SARS-CoV-2 variants, removing a roadblock in COVID-19 therapeutic development.

Immunotherapy has revolutionized cancer treatment, yet the drug discovery process to develop new biotherapeutic antibodies remains arduous. However, significant advances in antibody technology such as phage display have enabled fully human antibodies to be developed from animal-free libraries for just about any antigen.

As SARS-CoV-2 becomes an endemic agent worldwide, communities and health agencies must figure out how to identify novel variants and track infection rates in ways that are sustainable, sensitive, and accurate. Fortunately, wastewater-based epidemiology (WBE) has proven its ability to play an important role in monitoring COVID-19 outbreaks, and Droplet Digital PCR (ddPCR) has become a cornerstone method for ongoing wastewater-based disease surveillance. In this article, we review the role of wastewater-based testing in community health before, during, and beyond the COVID-19 pandemic, and we explore why ddPCR technology is ideally suited for this application as it continues to expand and evolve.

Cancer remains a leading cause of death worldwide. However, as cancer treatments continue to improve and diagnoses happen sooner, more and more patients are experiencing remission. To further increase survival rates and reduce unnecessary treatment, scientists and clinicians are turning to ultra-sensitive molecular analysis to inform treatment decisions and predict and detect relapse.

As technology advances, a digital transformation has begun in laboratories around the world. Driven by the need to improve data quality and increase the value derived from the investment in generating those data, data management systems, devices, and their workflows are becoming more connected and integrated, ushering in the age of the digital laboratory. The digital laboratory is one where paper lab notebooks are replaced with fully digital data, complete with rich metadata, and generated using integrated workflows. Such data are easy to find, reuse, and reproduce. Further digitization and workflow integration to operate laboratory instruments will advance the burgeoning digital laboratory.

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.
