(A)CTLL-2 cells cultured in 1640, stimulated with 10ng/mg IL2 for 48h; (B)UNstimulated CTLL-2 cells cultured in 1640.
The dose-effect curve of CTLL-2 was shown in Figure 2. It was obvious that CTLL-2 significantly promoted cell proliferation of CTLL-2 cells. The ED50 for this effect is typically 1.992 to 6.663 ng/mL.
