Encapsulation of macromolecules by lipid vesicles under simulated prebiotic conditions

Encapsulation of macromolecules by lipid vesicles under simulated prebiotic conditions

D W Deamer et al. J Mol Evol. 1982.

Abstract

Phospholipid vesicles (liposomes) were subjected to dehydration-hydration cycles in the presence of 6-carboxyfluorescein or salmon sperm DNA. We found that the vesicles fused into multilamellar structures during dehydration with solutes trapped between the lamellae. Upon rehydration the lamellae swelled and formed large vesicular structures containing solute. This model can be used to study encapsulation of macromolecules by lipid membranes to form protocellular structures under prebiotic conditions.
