Using the Purity Quotient Difference to Assess Protein Purification (PDF)

Pointing to the continued circulation and evolution of COVID-19, WHO published a statement on the COVID-19 vaccine antigen composition to respond to variants of the virus.

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.

EMA and HMA have published revised guidelines on identification of commercially confidential information and personal data used in marketing authorization applications.

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.

Contract development and manufacturing organizations (CDMOs) are more critical than ever as the demand for advanced therapies continues to grow.

BioPharm International sat down with Jean-François Vincent-Rocan, Director of Complex Chemistry Process Development at BIOVECTRA, to discuss antibody-drug conjugate (ADC) manufacturing. Due to their complex manufacture and supply chain management, JF emphasizes the need for a company that greatly understands the challenges and offers solutions that maintain quality and reliability. He also mentions what advancements are to come in this field and how best to stay ahead of a rapidly growing treatment option.
