Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Inhibitory Concentration (IC50) > 1000.00 ng/mL High CD30 expression (CD30+++; 400,000 CD30 molecules/cell)
Method Description
Serial dilutions of ADCs in cell culture media were prepared at 4x working concentrations, and 50 uL of each dilution was added to the 96-well plates. Following addition of test articles, cells were incubated for 4 days at 37°C, after which growth inhibition was assessed by the addition of CellTiter-Glo and luminescence was measured on a plate reader.
