Sepax spinoculation is suitable for patient samples. T-cells were prepared in the same manner as in Fig. 2, however only a 2-h bag centrifuge, 1-h Sepax, Static bag, and UNT CTRL groups were used. Patient CD19/22 CAR T-cells were produced with all three methods. Representative transduction efficiencies (A) and cumulative transduction data (B) on day 9 is shown. C T-cell fold expansion from day 4–9 was calculated. D VCN was calculated using ddPCR. E Viability was tested using AOPI. F CD4/8 frequencies were obtained by flow cytometry and plotted
