The effects of Mag2 (A,B) and Mag-A (C,D) on the molecular order of planar DMPC (A,C) and DMPC/DMPG (4:1) (B,D) bilayers determined by the optical birefringence as a function of total mass (ng/mm2) of lipid + membrane-bound peptide.
The peptides were injected consecutively onto the bilayer with a 2 fold increment in concentration. Solid arrows denote peptide association while dotted arrows correspond to peptide dissociation. 
= minimum value observed for Δnf. * = Δnf value at initial membrane disordering was observed. ** = Δnf value at which membrane disruption/mass loss was observed.
