Method "Oxygen transport in phosphatidylcholine-cholesterol membranes has been studied by observing the collision of molecular oxygen with nitroxide radical spin labels placed at various distances from the membrane surface using long-pulse saturation recovery ESR [electron spin resonance] techniques."
Comments "The permeability coefficient of oxygen across the membrane was evaluated in an approximate manner using Eq. 4 link by assuming that oxygen diffusion in the membrane is isotropic. The integration was performed based on figures such as Fig. 4: PM [permeability coefficient] was determined from the mean of the maximal area (under the solid line) and the minimal area (under the broken line), which takes the uncertainty of the location of the spin-label nitroxide group into account (ref 21). For details, see the legends to Fig. 4 and to Table 1." See notes beneath table
