Fig. 1.
ADA enzyme activity in various cells from the patients.
The columns indicate the geometric mean of ADA activity (U; nmol/min/108 cells) and the positive error bars indicate the SDs. Negative controls except for T-cell line are obtained from another ADA-deficient patient before the gene therapy.5TJF2 cell line15 was used as negative control for T-cell line. Note that only T-cell lines from the patients show elevated enzyme activity.
