Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Inhibitory Concentration (IC50) > 10.00 nM Positive ROR1 expression (ROR1+++/++)
Method Description
In a 96-well plate, each well was seeded with 4,000 to 5,000 of the respective cancer cell lines. After culturing for 24 hours, they were treated with the ADCs at a concentra-tion of 0.0015 to 10.0 nM (serially diluted threefold). 72 hours later, the number of live cells was measured using WST-8.
In Vitro Model Mantle cell lymphoma JeKo-1 cells CVCL_1865
Experiment 2 Reporting the Activity Date of This ADC [1]
