Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Inhibitory Concentration (IC50) 6.76 pM Positive CD38 expression (CD38+++/++)
Method Description
Cells were plated at about 500 cells per well in a 96-well plate in 100 uL of media. In vitro activity and targeted delivery of ADCs, the isotype-matched negative controls ADCs, and naked antibodies control were assessed in cells.
In Vitro Model Plasma cell myeloma NCI-H929 cells CVCL_1600
