π-area isotherms of different subphase concentration of lysozyme interaction with (a) DPPC and (b) DPPE monolayer. (i) Pure DPPC; (ii), (vii) 0.10 mM; (iii), (viii) 0.21 mM; (iv), (ix) 0.63 mM; (v), (x) 1.04 mM; (vi) pure DPPE. ΔA = A_ξ −A₀, where A₀ stands for mean molecular area of pure lipid monolayer and A_ξ is the mean molecular area of the mixed monolayer.
