Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Maximum inhibition efficiency (MIE) 66.00 pM Moderate MET expression (MET++; IHC H-score=180)
Method Description
Cell viability was determined by measuring the luminescence after adding the CellTiter-Glo 2.0 reagent. Cancer cells were seeded overnight in growth media and incubated at 37°C, 5% CO2,and 95% humidity. starting with concentrations of 100 nM for ADCs for free drug. Cells were exposed to test articlesfor 5 days.
