On the day of administration, HER2 targeted ADC and HER2 were prepared at a 10 fold ratio in standard growth medium. Add the prepared targeted ADC treatment to cells to obtain a final concentration of 3.81e-5nM to 100nM and a final volume of 50uL/well. Each drug concentration is tested in quadruplicate. On the same day, the cell viability of untreated cells at the time of administration was evaluated by adding 25 u L of CellTiter (ProMag catalog number G7573), a reagent for lysing cells and measuring total adenosine triphosphate (ATP) content. Incubate the plate at room temperature for 10 minutes to stabilize the luminescence signal before reading. Use luminous readingThe PHERAstar FSX ELISA reader (BMG Labtech) was used to measure the luminescence signals of all plates. This signal represents the cell viability of untreated cells on the day of administration or day 0.
