Functional characteristics of CAR T-cells are not affected by spinoculation. Cryopreserved CD19/22 CAR T-cells from a healthy donor, patient, and CD22 CAR T-cells were thawed and co-cultured with NALM6 tumor cells. 1:1 and 5:1 ratio of CAR T-cells to tumor cells were cultured together for 24 and 48 h. A–C Tumor Cell Counts per well calculated from cell counts and flow cytometry for healthy donor CD19/22 CAR T-cells (A), patient CD19/22 CAR T-cells (B), and healthy donor CD22 CAR T-cells (C). IFNγ ELISA’s were performed to measure the cytokine levels produced by the T cells in the supernatant for healthy donor CD19/22 CAR T-cells (D), patient CD19/22 CAR T-cell (E), and healthy donor CD22 CAR T-cells (F). Mean and SD of triplicate wells are shown.*Indicates p ≤ 0.05, ***Indicates p ≤ 0.001, ****Indicates p ≤ 0.0001 between the comparison of Sepax and centrifuge; and the static and Sepax groups
