Evaluation of toxicity of Mo-CBP3-PepI to human cell lines by MTT viability assay. In (A) L929, (B) HaCaT, and (C) MRC-5 lines were incubated with synthetic peptides at a concentration of 1 mg mL⁻¹. Methyl methanesulfonate (MMS; 4 × 10⁻⁵ M) was employed as a positive control for cell toxicity, and healthy cells as a negative control for toxicity. Data are shown as mean ± standard deviation of three independent experiments with significance of p < 0.05. Small letters indicate statistical significance.
