Experiment 1 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Inhibitory Concentration 5% (IC5)	110.00 ng/mL	Positive GPC3 expression (GPC3+++/++)
Method Description	Ten thousand cells were seeded in a 96-well cell culture plate (200 l per well), supplemented with purified immunotoxins at the indicated final concentrations, and incubated at 37°C for 3 days. Cell viability was determined by quantifying the enzymatic activity of the intracellular luciferase that was released by two rounds of freezing-thawing. Click to Show/Hide
In Vitro Model	Hepatocellular carcinoma	G1LG cells		Homo sapiens
Experiment 2 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	7.90 ng/mL	Positive GPC3 expression (GPC3+++/++)
Method Description	Ten thousand cells were seeded in a 96-well cell culture plate (200 l per well), supplemented with purified immunotoxins at the indicated final concentrations, and incubated at 37°C for 3 days.
