Toward Redosable Gene Therapy: Engineering AAVs to Evade T‑Cells
Adeno-associated virus (AAV) vectors are widely used in gene therapy because of their ability to enable long-term transgene expression with favorable safety profiles. However, immune responses to the AAV capsid remain a major barrier, limiting treatment durability and the feasibility of repeat dosing. A recent Nature Communications study led by Dr. Ronit Mazor and colleagues

Charge Detection Mass Spectrometry (CDMS): Unprecedented Direct Measurement for the Characterization of Mega-Mass Biomolecules
Whether you are analyzing adeno-associated viruses (AAVs) or virus-like particles, nucleic acids such as RNAs or lipid nanoparticles (LNPs), proteins, or protein complexes, simple and fit-for-purpose tools with speed, accuracy, and precision are essential for driving biotherapeutic innovations forward. In recent years, scientists have increasingly turned to charge detection mass spectrometry (CDMS).
Navigating the Hidden Threats: Managing Particulate Contamination in Cell Therapy
In the realm of cutting-edge medical treatments, cell therapy products have emerged as revolutionary tools in combating a myriad of diseases, ranging from cancer to genetic disorders. These therapies harness the power of living cells to regenerate damaged tissue, modulate immune responses, or directly target malignant cells. However, amidst the promise of these novel treatments...
Early Detection of Glass Delamination: Why BMI is the Best Tool
Glass delamination has been a persistent challenge in the pharmaceutical industry, posing risks to drug stability and patient safety. The phenomenon occurs when shiny, thin glass layers (lamellae) detach from the interior surface of a glass container and float in the contact liquid. These subvisible glass particles (SVGPs) can cause serious health risks, including infusion-related complications....
Beyond Impurities: Why Today’s Biologics Need Smarter Particle Analysis
Particle analysis is not just a requirement in biopharmaceutical development—it’s a critical component that can make or break the safety and efficacy of your drug. When developing protein therapeutics, particles like aggregates over 1 µm must be defined and monitored, while in delivery systems, even the vehicles themselves—cells or viruses—qualify as particles. Ignoring or mismanaging...
