General Information of The Activity Data Related to This ADC
Full List of Activity Data of This Antibody-drug Conjugate
Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Half Maximal Effective Concentration (EC50) | 0.222 nM | Positive ROR1 expression (ROR1+++/++) | ||
| Method Description |
Ntera-2 cell at 625 cells/25 pL were seeded in a 384-well plat. ADCs were formulated at 2x starting concentration. Filter sterilized samples were serial diluted (1:3) under sterile conditions and added onto cells in triplicates. For cell viability measurement, 30 microliter of Cell Titer-Glo@ reagent (Promega Corp, Madison, WI) was added into each well, and plates processed as per product instructions.
