Table 1. Relative permeability rates of antibiotics through Omp38 porins.
Permeability rates of antibiotics were calculated relative to the rate of L-arabinose (Mr 150), which was set to 100%.Values given as mean values±S.D. are obtained from three independent assays, and liposomes with BSA and liposomes without any protein were used as negative controls.
