Measured (symbols with error bars) and computed (line) tumor volumes with time of A431/H9 (A) and ATAC-4 (B) cell tumors growing in nude mice.

The experimental data are from Zhang et al. [7] and Singh et al. [15]. In each panel, the black line and symbols are for control with no immunotoxin and the red line and symbols are for the case when immunotoxin was given three times, at times indicated by the black arrows. The dose level was 200 µg/kg (62 nM) for SS1P (panel A) and 160 µg/kg (51 nM) for LMB-2 (panel B).
