Experiment 1 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	10.00 pM	Positive FOLR1 expression (FOLR1+++/++)
Method Description	Conjugates or free drug compounds were diluted in RPMI-1640 supplemented with heat-inactivated 10% FBS and 0.1 mg/ml gentamycin , and added to the plated cells. To determine specificity of cytotoxic activity of the conjugates an excess of unconjugated antibody was added to a separate set of diluted conjugates.
In Vitro Model	Human papillomavirus-related endocervical adenocarcinoma	KB cells		CVCL_0372
Experiment 2 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	0.10 nM	Negative FOLR1 expression (FOLR1-)
Method Description	Conjugates or free drug compounds were diluted in RPMI-1640 supplemented with heat-inactivated 10% FBS and 0.1 mg/ml gentamycin , and added to the plated cells. To determine specificity of cytotoxic activity of the conjugates an excess of unconjugated antibody was added to a separate set of diluted conjugates.
In Vitro Model	Invasive breast carcinoma	T-47D cells		CVCL_0553
