Penetration efficiency of different dextran molecules and oligopeptides into ovine vitreous humor. The concentrations of dextrans (a) and peptides (b) in ovine vitreous humor are shown after incubation of the vitreous samples overnight in different dextran/peptide solutions. DEAE (polycationic), unmodified (neutral), and CM (polyanionic) dextrans are compared at two different molecular masses (a). The sequence of the peptides P1–P7 (b) is described in Materials and Methods and in the Supporting Material. The error bars denote the standard deviation as obtained from three vitreous samples. Asterisks denote statistically significant differences (^∗∗∗p < 0.001). To see this figure in color, go online.
