Chitosans samples have no cytotoxic effect on PK15 cells. PK15 cells were pretreated with different concentrations of Chi-S and Chi-C for 24 h at 37 ℃, and then add 10 μL of CellTiter 96® AQueous One Solution MTS (Promega Corporation) to each well for 1 h at 37 ℃ and measured absorbance at 490 nm. All data were presented as means ± SD and were analyzed using one-way ANOVA (ns = no significant)
