In the ever-evolving landscape of drug development, biomarkers have emerged as critical tools for the mechanism of action, early proof of mechanism, safety, predictive, efficacy, and monitoring treatment response. As the field advances, two major classes of biomarkers have come to the forefront: soluble biomarkers and cellular biomarkers. While…

In the process of drug discovery, an IC₅₀ assay serves as a pivotal component in the development of cutting-edge therapeutics. An effective assay can quantify the potency of compounds, enable side-by-side comparisons with competing compounds, and track how a compound performs over time. Quantifying compound inhibition also assists with pre-clinical…

PCR-based assays are increasingly utilized for bioanalysis to support the development of a wide variety of therapeutics. While the largest driver for this growth has been the expanding pipeline of cell, gene, and RNA therapies, PCR-based assays are also seeing increased use in biomarker detection across all therapeutic modalities. These…

Remember that childhood excitement the night before Christmas? Too excited to sleep, knowing something you wished for was finally within reach? That’s exactly the spirit fueling our teams in Lyon as we approach the end of June. We’re eagerly awaiting the arrival of a powerful new platform at our…

Hybrid LC-MS/MS is a technique that combines an affinity capture step with LC-MS/MS detection. It typically requires only one antibody, in contrast to conventional ligand-binding assays (LBAs), which usually need two. This approach leverages the combined selectivity of affinity extraction and the analytical power of tandem mass…

Biomarkers (BMKs) have become fundamental tools in drug development, accelerating and optimizing targeted therapeutic innovation. As a bioanalytical CRO with over 15 years of experience in biomarker analysis, we’ve seen firsthand how the strategic integration of biomarkers can accelerate drug programs, help meet evolving regulatory standards,…
