a Flow cytometry analysis of SNAP receptor activation for SNAP-synNotch and SNAP-CAR cells co-incubated with target cells that were pre-labeled with the indicated antibodies. b Flow cytometry analysis of SNAP receptor activation for SNAP-synNotch and SNAP-CAR cells that were pre-labeled with the indicated antibodies and co-incubated with target cells. TagBFP output gene expression and CD25 marker expression were evaluated by flow cytometry. c Specific lysis of target cells by co-incubated primary human SNAP-CAR T cells that were pre-incubated with the indicated concentration of adaptor at the indicated cell concentration as compared to SNAP-CAR T cells incubated with 1.0 μg/mL of soluble adaptor or a positive control anti-CD20 CAR. For a and b, two-way ANOVA tests with multiple comparisons were performed. As the data did not have homogeneity of variance (Levene’s test), Tukey’s HSD was used for post-hoc analysis between antibody conditions. “ * ” denotes a significance of p < 0.0001, n = 3 biologically-independent experiments ± s.e.m. For c a one-way ANOVA with Dunnet’s Multiple Comparison tests was performed and all values were significantly different (p < 0.0001) from the no adaptor control (white bar). Source data are available as a Source Data file.
