The Maxpar Human T Cell Expansion Kit is designed for use with fresh or frozen human whole blood or PBMCs in combination with the Human T Cell Phenotyping Panel Kit. The kit 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. When combined with the 16 antibodies in the Human T Cell Kit, the 10 antibodies in the Human T Cell Expansion Kit allow for comprehensive identification of 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, and for the classification of the activation and homing status of these subtypes.
