Chimeric antigen receptor T cells (CAR T cells) therapy is one kind of immunotherapy that has revolutionally changed the landscape of immunotherapy and been approved by the FDA from 2017 for several blood malignancies. To bring new CAR T cells to clinic, every new CAR need to test in vitro for antigen recognition, tumor cell killing capacity, and off-target cytotoxicity effect. Detecting the secretion of cytokines upon engagement of CAR T cells with tumor antigens is routinely applied to assess these CAR functions. Here we describe coupling of intracellular cytokine staining and multicolor flow cytometry to measure CAR T cells activation upon antigen stimulation.
