Description
Analysis of HER2-amplified NCI-N87 gastric cancer cell line exposed to 0.1 g/mL T-DM1 and subsequently cultured in the presence of gradually increasing doses, up to a maximum of 4 g/mL. The resultant cell lines that grew exponentially in the presence of T-DM1 were designated as drug resistant gastric cancer cell lines, and named N87-TDMR.
