Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Half Maximal inhibitory Concentration (lC50) |
0.05 nM
|
Positive TF expression (TF+++/++) | ||
| Method Description |
The TF-specific ADCs were added to HPAF-II cells, with either a 72 h incubation or a 4 h incubation followed by removal of excess ADC and culture for another 74 h. HPAF-II cells were lysed in CTG assay reagent after treatment.
