Migration distances of (A) MUC5AC and (B) MUC5B mucins from CF-HBE culture washings following treatment with modified chitosan oligosaccharides for 1 h at room temperature. The migration distances of mucin treated with equal volumes of PBS are denoted with dashed horizontal lines. All values are presented as the mean ± standard deviation for 3 or more pooled experiments. Asterisks (*) indicate significant differences (p < 0.05) relative to treatment with PBS (0 mg/mL).
