Determining Protein Concentration, Part 1: Methodology

Christopher Murphy, director of Global Business Development and Service Customer Support at Environmental Specialties, sat down with the PharmTech Group at INTERPHEX 2025 to discuss the design and critical role of walk-in chambers in the bio/pharmaceutical industry.

In this episode, we explore BIOVECTRA’s capabilities in antibody-drug conjugate (ADC) manufacturing, from complex conjugation chemistry to synthesis of highly potent payloads. We’ll also showcase how BIOVECTRA’s extensive experience in complex chemistries and specialized small molecule manufacturing gives them a unique perspective, strengthening their approach to ADC production and ensuring clients receive custom solutions across all project stages.

Speaking at INTERPHEX 2025, William Wainwright, business development manager at Iwata Label USA, discusses the practical benefits of functional labels in protecting parenteral drugs.

Metabolic Flux Analysis (MFA) is a powerful technique used to characterize metabolic phenotype driving to improved productivity in biomanufacturing. MFA is most powerful when absolute concentrations of the metabolic intermediates are measured, but doing so in practice is often impractical due to inherent limitations of conventional absolute quantitation by mass spectral analysis. Recently, advances in artificial intelligence (AI) have been applied to solving the problem of broad, untargeted, absolute quantitation in liquid chromatography-mass spectrometry (LC-MS). These new approaches extend readily to the determination of absolute concentrations of stable isotopically-labeled metabolic intermediates, offering a new tool for MFA. Dr Sam Yenne from Metalytics Inc., a company that specializes in the science of metabolic flux, has recently assessed and adopted Pyxis, a new tool for absolute quantitation of raw LC-MS data. Dr Yenne describes MFA, its utility in biopharmaceutical development, associated challenges and how Pyxis impacts those challenges.

BioPure’s BioClamp connector has been upgraded and is now manufactured to be 13% lighter than the previous model, allowing users to achieve a 26% reduction in carbon dioxide emissions across the full lifecycle of a product.

Martin A. Makary, confirmed by a bipartisan vote of the US Senate, has been sworn in as FDA’s new commissioner.
