Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Inhibitory Concentration (IC50) 0.80 uM Positive CD74 expression (CD74+++/++)
Method Description
Briefly, cells were placed in 96-well plates (2 x105 per well) and subsequently incubated with serial dilutions of IMMU-110,naked hLL1,nonspecific negative control mAb-drug conjugate (hRS7-doxorubicin),or nonspecific mAb (hRS7) on ice for 1.5 hours. 4-hour IC50 values of IMMU-110,hRS7-doxorubicin,and free doxorubicin against the multiple myeloma cell line (MC/CAR) and other CD74-positive non-Hodgkin's lymphoma cell lines (Daudi and Raji).
