Permeability coefficients for metabolites and oxygen (PmO2) in presence of a polyamide membrane (pore size 0.2 μm) with and without mucus layer (200 μm) (n = 2)
Polyamide membrane FITC dextran Oxygen
4 kDa 20 kDa 150 kDa
With mucus 2.4 ± 10−6 2.5 ± 10−7 7.1 ± 10−9 2.5 ± 10−4
Without mucus 5.6 ± 10−6 4.1 ± 10−7 6.5 ± 10−7 NDa

aND = not determined.

Data are expressed as cm sec−1. The permeation coefficient was lower in presence of the mucus and with the increase of the FITC dextran kDa.
