Permeability of membranes used for MailPan^® is suitable for insulin-secreting cells encapsulation: (a) Permeability of membranes to glucose, insulin, and IgG assessed in static conditions after 24 h of incubation at 37°C, mean ± SEM, n = 6 for each molecule; (b) permeability of membrane to fluorescent dextran related to molecular weight, in static conditions after 24 h of incubation at 37°C. The horizontal dotted line represents the cut-off threshold set at 5% of permeability, mean ± SEM, n = 6 for each Dextran size; (c) pores size measurement by liquid–liquid porometry performed on five membrane samples; and (d) representative distribution of pore size on membrane samples tested.
