Experiment 1 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	14.80 nM	Positive HER2 expression (HER2 +++/++)
Method Description	N87 cells (10000) were seeded in 96-well plates for the IC50 measurements of cell viability. After incubation at 37°C for 16 h, the medium was replaced by fresh normal medium with serum and the cytotoxicity was assessed using the WST-1 reagent after 72 h of incubation at 37°C.
