Low dose effects of melittin on dilute suspensions of dipalmitoylphosphatidylcholine multilamellar vesicles are investigated by studying the acoustic properties of the system. The temperature dependencies of sound velocity and absorption have been measured at 7.2 MHz in the temperature range of 20-55 degrees C, for different peptide/lipid molar ratios, R. The most pronounced effects were observed at R = 5 x 10(-3), in the vicinity of the pretransition, with a simultaneous increase in sound… CONTINUE READING
