Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (lC50)
8.01 nM
Positive PD-L1 expression (PD-L1+++/++)
Method Description
The starting point of the small molecule drug was 500 nM, and the drug was diluted 5 times sequentially, for a total of eight concentration points. Cells were laid on 96-well plate at 4000 cells/well, cultured overnight and were added with diluted drugs, in the incubator for 72 h. All cells incubated with the drug were tested for cell viability using Cell Counting Kit-8 (CCK-8) kit (Meilunbio, Dalian, China).
