Evaluation of CD30 expression on T cells during the generation of EBV-CTLs and on CD30CAR⁺ EBV-CTLs

	Stimulation
	First	Second	Third	Fourth or more
CD3+ T cells/EBV-CTLs	14 ± 8	5 ± 4	6 ± 6	3 ± 5
CD30CAR+ EBV-CTLs	3.7 ± 1.8	7.2 ± 5.5	7.3 ± 4.5	1.8 ± 0.4

Data are percentages of T cells. Evaluation of CD30 expression on CD3⁺ T cells/CTLs and on CD30CAR⁺ CTLs 5 to 7 days after the indicated stimulation with autologous LCLs. Analysis was performed by FACS after staining with CD30 PE-labeled MAb. CD30 expression on circulating T cells is less than 1%.
