MTT colorimetric assay of viable hTM cells in the presence of XFS-specific peptides in free and conjugated form. (Left) MTT assay conducted using peptide-conjugated MPs. (Right) MTT assay results after incubation of hTM cells for 24 h with 0.5 mM and 1 mM free peptide solutions. The optical density was measured at 570 nm after 24 h incubation of hTM cells with each test sample. (Data represent mean ± 1 SD, n ≥ 3, no statistical difference was observed between the means)
