Click To Hide/Show 2 Activity Data Related to This Level

Experiment 1 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	0.83 nM	Positive MUC16 expression (MUC16 +++/++)
Method Description	Cells were seeded in 96 well plates at 3000 cells per well in complete growth media and grown overnight. For cell viability curves, serially diluted conjugates or payloads were added to the cells at final concentrations ranging from 300 nM to 5 pM and incubated for 8 days.
In Vitro Model	Ovarian serous adenocarcinoma	OVCAR-3 cells		CVCL_0465
Experiment 2 Reporting the Activity Date of This ADC					[1]
Efficacy Data	Half Maximal Inhibitory Concentration (IC50)	> 100 nM	Negative MUC16 expression (MUC16-)
Method Description	Cells were seeded in 96 well plates at 3000 cells per well in complete growth media and grown overnight. For cell viability curves, serially diluted conjugates or payloads were added to the cells at final concentrations ranging from 300 nM to 5 pM and incubated for 8 days.
In Vitro Model	Normal	HEK293 cells		CVCL_0045
