Effect of endosomal inhibitors on the entry of peptide NRPDSAQFWLHH into A431 cells. (a) A431 cells were pre-incubated with different endosomal inhibitors, and in the presence of fluorescein-labelled peptide NRPDSAQFWLHH. Endosomal inhibitors are labelled on the left of figure. (b) MTT assay showing the viability of A431 cells in the presence of inhibitors. Data are expressed as mean ± standard deviation (n = 3).
