In Vitro and Ex Vivo Models
Mechanistic and functional studies in human and murine immune cells
Our in vitro and ex vivo services are a key part of Redoxis’ preclinical CRO offering, supporting target validation, mechanism-of-action studies, candidate comparison and biomarker development. Capabilities include immune-cell assays, functional profiling, cytokine analysis, flow cytometry, ELISpot and FluoroSpot, molecular analyses and tailored co-culture systems.
Our work is built on reproducible methods, biological relevance, and flexibility.
