This panel set contains one each of the Maxpar^® Human T Cell Immuno-Oncology Expansion Panel Kit, Maxpar Human T Cell Phenotyping Panel Kit and Maxpar Human T Cell Phenotyping Expansion Panel Kit. It enables mapping of the expression patterns of the eight included checkpoint and activation markers on all major T cell subsets, including naïve, central memory, effector and effector memory CD4+ and CD8+ cells; naïve and memory Tregs; and Th1 and Th2 cells. The combined panel also enables the classification of the activation and homing status of these T cell subsets. The panel set contains all the reagents needed to run a CyTOF^® experiment, including buffers optimized for staining and a nucleic acid intercalator used for single-cell identification.
