Protein-liposome conjugates

摘要

A lipid coupling reagent for use in coupling amine-containing molecules, such as proteins, to liposomes. The reagent includes phosphatidylethanolamine coupled to a 3-20 atom carbon-containing spacer arm terminating at a carboxyl or thiocarboxyl group. Also disclosed are liposomes prepared to include between about 1 and 20 mole percent of the coupling reagent, and liposomes containing surface arrays of proteins attached to the liposomes through the coupling reagent.
