Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Effective Concentration (EC50) 30 pM Positive HER2 expression (HER2+++/++)
Method Description
Proliferation assays revealed EC50 values in double-digit picomolar range for all constructs on high HER2 expressing cell line SK-BR-3 (Figure 3a, Table 2) which was found to be comparable or significantly lower than for Cp-bearing ADCs found in literature
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 Effective Concentration (EC50) 515&#177195 pM Moderate HER2 expression (HER2++)
