(I) Incubate MCF-7 cells seeded in a 12-well plate for 24 h with multiple concentrations of paclitaxel. (II) Aspirate the cell medium in the 12-well plate, wash the cells with 1 mL of DPBS, and aspirate it again. (III) Add 100 µL of trypsin to the sample and incubate it for ~5 min at 37 °C. (IV) Add 1 mL of complete medium to the sample to dilute the cell suspension and mix it by pipetting up and down a few times with a micropipette to break up any clumps of cells. (V) Place a 40-µm cell strainer on top of a 2-mL conical tube. Pass cells through the cell strainer to remove clumps and debris. (VI) Put the single-cell suspension into a 1-mL syringe and load the syringe on a syringe pump.
