Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (lC50)
0.114 nM
Positive HER2 expression (HER2+++/++)
Method Description
Cells were seeded in their growth media into 96 well plates (Thermo #136101) one day prior to adding ADCs: 1000/well SK-BR-3 cells in 80 uL media (target positive cells). 20ul assay media diluted ADC/ isotype conjugates (1:4 10 pts starting from 100uM) as well as free drug were transferred to above cells. The plates were incubated at 37°C, 5% CO2 for 6 days.
