Effect of 89Zr-oxine on cell viability and proliferation of CAR-Jurkat and CAR-T cells. A Cell viability of radiolabeled and unlabeled CAR-Jurkat and CAR-T cells was determined at different time points by trypan blue exclusion technique. B Cell proliferation of radiolabeled and unlabeled CAR-Jurkat and CAR-T cells was determined at different time points by MTS cell proliferation assay. C Cell associated radioactivity was measured after spinning 1 × 106 CAR Jurkat and CAR-T cells to determine retention of radioactivity at different time points. Three independent experiments were performed in triplicate and results were expressed as mean ± SD
