Phe insertion assay data analysis. a Steady-state ΔA/A as a function of π for DPPE and DPPC monolayers on water (open circles and squares, respectively) and PBS (filled circles and squares, respectively). b Steady-state ΔA/A as a function of π on a semilogarithmic scale. Solid lines are linear fit to the data. From the slope of linear fits, two different values for APhe were obtained. For the DPPC monolayer on PBS (filled squares, slope = − 112 ± 7), a value of 48 ± 3 Å2 was found for APhe with eq.1. For other monolayers, a value of 33 ± 2 Å2 was found for APhe from the virtually identical slopes of − 77 ± 2, − 76 ± 3 and − 78 ± 2. The data are for DPPE and DPPC monolayers initially at 52 ± 4 and 65 ± 5 Å2/molecule, respectively
