Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (lC50)
2.028&#1770.4680 nM
Positive SLCA2 expression (SLCA2+++/++)
Method Description
The MTT assay was performed to determin the in vitro efficacy of the 19G4-MMAE ADC. Cells were seeded in 96-well plates at a density of 5000 cells/well for SCC15, NPC/HK1, FADU, C666-1 at 37 °C and 5% CO2 overnight. Dilutions of PBS, 19G4, IgG-MMAE, and 19G4-MMAE solutions were added to cells for 72 h incubation at 37 °C. Cell viability were evaluated in triplicate by MTT assay. The IC50 was determined using Graphpad Prism version 9 (GraphPad Software, Inc.).
