Figure S2. Determination of appropriate puromycin concentration. (A) The growth state of CHO-K1 cells in F12k media under different puromycin concentrations and incubation times. (B) The viability of CHO-K1 cells under different puromycin concentrations and incubation times. The appropriate puromycin concentration was defined as the lowest concentration that kills 100% of the cells in 7 days.
