Abstract: Agents for inhibiting adsorption of proteins on the liposome surface and liposomes which are agglutination-free by binding said inhibiting agent on the surface are disclosed. The above-mentioned inhibiting agents comprise a hydrophobic moiety and a hydrophilic macromolecular chain moiety. Adsorption of plasma proteins on the liposomes is inhibited due to the hydrophilic moiety exposed on the liposome surface with a result that agglutination of the liposomes in plasma is prevented.

Accordingly, the liposomes are especially highly useful as artificial erythrocytes for which a large dose of liposomes is needed for administration.
