In this application note, Olink Proteomics discusses the use of blood biomarker profiling to accelerate immunotherapy development. Olink also introduces the Olink Flex ® Immuno-Oncology panel, which includes 21 proteins involved in tumor development and the immune response. Some of these biomarkers have shown clinical relevance in stratifying patients treated with immune checkpoint inhibitors. Blood biomarker profiling can provide real-time insights in a non-invasive, robust, and e
