| | NCI-N87 Cell Viability Assay for Antibody-Polymer-Drug Conjugates |
| Description: | PBD compounds and conjugates thereof were evaluated for their antiproliferation properties in tumor cell lines in vitro using CellTiter-Glo (Promega Corp). Cells were plated in black walled 96-well plate and allowed to adhere overnight at 37° C. in a humidified atmosphere of 5% CO2. NCI-N87 cells (HER2 expressing cells) and were plated at a density of 5,000 cells per well. The next day the medium was replaced with 50 μL fresh medium and 50 μL of 2× stocks of PBD compounds or antibody-PBD conjugate were added to appropriate wells, mixed and incubated for 72 h. CellTiter-Glo reagent was added to the wells at room temperature and the luminescent signal was measured after 10 min using a SpectraMax M5 plate reader (Molecular Devices). Dose response curves were generated using SoftMax Pro software. IC50 values were determined from four-parameter curve fitting. |
