Abstract

Chimeric antigen receptors against CD19 (anti-CD19-CAR) are widely recognized and used by not only researchers associated with immunology, molecular biology, and cell biology but also physicians to treat B-cell malignancies. Anti-CD19-CAR is currently clinically available as one of the therapeutic modalities for refractory acute B-cell-typed lymphoblastic leukemia (B-ALL) patients. However, to detect CAR on the cell surface and investigate the efficacy of CAR-T cells, there are numerous experimental modalities including flow cytometry, the Cr-releasing assay, immunoblot, and immunostaining. We have chosen several techniques, which are necessary and sufficient as well as reliable and reproducible to detect and assess the killing effect of CAR-T cells. Here, we describe protocols for basic experiments and procedures for the detection of CAR on transduced cells and in in vitro coculture experiments to assess cytotoxicity using CAR-T cells.
