Procedure

An air-water interface was prepared using peptide having SEQ ID NO:10 (5.0 μM in 25 mM Tris.HCl, 100 mM NaCl at pH 7.3). After aging, the interfacial elasticity modulus was 29 mN/m and the maximum interfacial stress was 0.5 mN/m. A mixed sodium phosphate, sodium citrate, sodium borate (PCB) buffer at pH 7.0 was then added to give bulk solution concentrations of 1 mM phosphate, 1 mM citrate, and 1 mM borate. After PCB addition and further aging, the interfacial elasticity modulus was 51 mN/m and the maximum interfacial stress was 1.4 mN/m at 39% strain.
