Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (IC50)Human PBMC 0.0181 nM Positive HER2 expression (HER2 +++/++)
Method Description
After sample addition, culture for 6 days. Thaw the CellTiter-Glo® reagent and place the cell culture plate at room temperature to equilibrate for 30 minutes. Then add 50 to each well. Shake and lyse the cell plate in a shaker for 2 minutes, then incubate at room temperature for 10 minutes to stabilize the luminescence signal.
In Vitro Model Breast adenocarcinoma SK-BR-3 cells CVCL_0033
Experiment 2 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (IC50)Human PBMC 0.0184 nM High HER2 expression (HER2+++; >300,000 HER2 molecules/cell)
Method Description
After sample addition, culture for 6 days. Thaw the CellTiter-Glo® reagent and place the cell culture plate at room temperature to equilibrate for 30 minutes. Then add 50 to each well. Shake and lyse the cell plate in a shaker for 2 minutes, then incubate at room temperature for 10 minutes to stabilize the luminescence signal.
