Protamine-induced adsorption of sodium pyrene-3-sulphonate (NaPyS) on the lipid monolayers

The interaction of sodium pyrene-3-sulphonate (NaPyS) with different lipid monolayers at the air-solution interface was studied by monolayer techniques (surface pressure and surface potential measurements) and by spectroscopic techniques (fluorescence and reflection measurements). The uptake of negatively charged NaPyS by non-charged and negatively charged phospholipid monolayers was induced by the presence of positively charged protein protamine in bulk solution.
