The cytotoxicity of CT83‐expressing cells following 7G4‐1‐Ga treatment. The cytotoxicity to CT83‐expressing cells in vitro were incubated for 1 hour with 1 μmol/L 1‐Ga or 5 μg/mL 7G4‐1‐Ga containing equivalent amounts of 1‐Ga, washed twice, then given PDT. As a result, in this condition, pretreatment with 1‐Ga slightly increased the killing activity. However, more than 20% ~ 60% of the cells were killed after incubation with 7G4‐1‐Ga. Values were represented as the mean ± standard error of the mean (SEM). **P < .01 and ***P < .001
