Figure 7. Cysteine and tryptophan are the most reactive amino acids towards the effective species in the CAPs DMEM.

Figure 7

Relative cell viability of U87 cells (a), MDA-MB-231 cells (b), and MCF-7 cells (c) cultured in the CAPs amino acids rich DMEM (2.4 mM). The treatment time for all figures was 1 min. Results are presented as the mean ± s.d. of three repeated experiments performed in sextuplicate. Student’s t-test was performed, and the significance compared with the bar of DMEM is indicated as *p < 0.05, **p < 0.01, ***p < 0.005. Red arrows mark the amino acids which are significantly weaken the anti-cancer capacity of CAPs media for three cell lines.
