Monitoring the quality and quantity of cellular immune responses in clinical immunotherapy trials aids in evaluating the efficacy of treatment. The nature of the cellular immune response generated could impact the further development of immunotherapeutics, also known as immunoguiding. High-parameter flow cytometry offers a tool addressing multiple markers on samples of different origin (e.g. blood, organs, tumor) containing a heterogeneous composition of cell types with a statistical robustness. This technology thereby creates immunological signatures for a variety of decisive descriptors, such as early failure, prognostic marker, predictive marker and/or substitute for clinical endpoint testing.
TRON’s immunomonitoring team operates a suite of flow cytometers with the capacity to capture tailored, multiple marker sets addressing different types of immune cells. This activity includes phenotyping, activation status and cytokine production profile upon stimulation of cells. Our scientists have set up multiple marker panels for different questions and provide consulting, analysis and data interpretation to internal colleagues and collaborations partners.
All the methods are established as standard operating procedures (SOPs) as a component of our internal quality assurance system.
