Methods of forming targeted liposomes loaded with a therapeutic agent

摘要

The present invention provides for liposomes loaded with a therapeutic agent, which liposomes are targeted to a cell of interest by incubation with a targeting protein protein conjugated to a linker molecule comprising a hydrophobic domain, a hydrophilic polymer chain terminally attached to the hydrophobic domain, and a chemical group reactive to one or more functional groups on a protein molecule and attached to the hydrophilic polymer chain at a terminus contralateral to the hydrophobic domain, for a time sufficient to permit the hydrophobic domain to become stably associated with the liposome.
