Immunophenotyping of CAR T cell activation using flow cytometry

MBTP 53 = Miltenyi Biotec-tested panel 53

This application protocol describes the analysis of chimeric antigen receptor (CAR) T cell activation. To demonstrate the state-of-the-art panel, CAR T cells were generated within 12 days using the CliniMACS Prodigy® T Cell Transduction process. CAR T cell activation was analyzed using Miltenyi Biotec’s automated data acquisition and analysis Express Mode program “CAR T Cell Express Mode Package”.
