title: Liposomes. Effect of temperature on their mode of action on single frog skeletal muscle fibers.
abstract: Liposomes containing the fluorescent dye 6-carboxyfluorescein were made from dipalmitoyl phosphatidylcholine and stearylamine. At 4 degrees C the liposomes are adsorbed on the fiber surface and when the temperature is raised to 21 degrees C, their contents are transferred directly into the fibers at a linear rate. Liposomes had little effect on the time course of the maximal twitch tension.
