Experiment 1 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	0.24 ng/mL	High HER2 expression (HER2+++; 694,000 HER2 molecules/cell)
Method Description	Briefly, cells were plated on 96-well plates in 75 uL growth medium and grown at 37°C in a humidified incubator in a 7.5% CO₂ atmosphere. After one day incubation, 25 uL of 3.5-fold serial dilutions of each ADC in growth medium were added, typically resulting in final ADC concentrations from 20 ug/mL to 0.02 ng/mL.
In Vitro Model	Breast adenocarcinoma	SK-BR-3 cells		CVCL_0033
Experiment 2 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	12.00 ng/mL	Moderate HER2 expression (HER2++; 32,000 HER2 molecules/cell)
Method Description	Briefly, cells were plated on 96-well plates in 75 uL growth medium and grown at 37°C in a humidified incubator in a 7.5% CO₂ atmosphere. After one day incubation, 25 uL of 3.5-fold serial dilutions of each ADC in growth medium were added, typically resulting in final ADC concentrations from 20 ug/mL to 0.02 ng/mL.
In Vitro Model	Invasive breast carcinoma	T-47D cells		CVCL_0553
