Formation and property of mixed vesicles of phosphatidylcholine and MDP derivatives.

The aggregation form of mixtures of phosphatidylcholine and MDP derivatives was studied. The mixed vesicles containing less than 40 % of B30-MDP were unilamellar, and over 40 % B30-MDP aggregates of mixed vesicles or oligolammellar vesicles appeared. The mixed vesicles containing less than 20 % of DV-7401 were unilamellar, and over 20 % of it fibriform structures appeared.
