Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Inhibitory Concentration (IC50) 24.20 ng/mL Positive CD33 expression (CD33+++/++)
Method Description
The cells, at a predeterminedconcentration, were plated into 96 well plates, and, after overnight incubation at 37°C/5CO2, serialdilutions of each test article (TA) were added to the cells. Cells were incubated with test articlesfor 72 hours, and viability was detected with CellTiter-Glo reagent.
