What is the Most Relevant Tissue Biomarker Assay for My Clinical Research Study?

Overview. In the early phase of clinical testing during drug development, researchers need to identify markers that best distinguish different patient groups, such as responders versus non-responders. At this stage, there are often many ideas about which markers, cellular phenotypes reflected by markers, or spatial interactions between them, might reveal these differences, but it’s important to narrow down this long list of possibilities to the most promising subset of markers.
